600 watt hps on 18-6
Change to 1000watt hps during flower
Tent 5x5
Temps are at 23 at night and 27.3 during the day
Humidity is at 65
13 litre pots
So I'm growing northern lights. This is probly my 5 grow with this particular strain and never had these issues before. I tried going with a different medium. Mine was out of stock. And everything has turned to custard. They have been in those pots for the 5 weeks during vege with barely any growth. I thought nutrients so I sorted ph (6.5) and gave some calmag just in case. I think I overwatered so I pulled soil out without damaging roots added more perlite and more drain holes soil is drying within 4 days and still nothing. Is there anything else I can do for these babies.. they are really lime green boarder line going yello

Definitely aren't too happy looking.
Need some more info on the soil-is it fortified?
I'm assuming because you've had previous runs, the only variable would be the soil.

what nutes?
how far up is the light ?
What soil brand ?
How old is the bulb?
What water source?

Well .....i would say that you did damage the roots since you messed with them.
If these are in flower you need to go back to veg cuz you wont get shit off of them.
I find it hard to believe that a small sick plant in a big pot like that ..they look big to me...would need to be watered in four days.

I thought nutrients so I sorted ph (6.5) and gave some calmag just in case
This sentence doesnt make any sense to me

Now I may be wrong but.......
Im under the impression that these have been over watered, not given any nutrients, haven't added any microbes. Which means root rot. or root issues no nutrients and no microbes to provide nutrients to the plant. No microbes to combat the root issues.

So...
mag makes the plant green, nitrogen makes it grow. Your plants are hell of low on mag.

Feed it some epsom salt, not cal/mag. Like about 350 ppms. add microbes to this. let that go for a while, till the pot actually needs to be watered again. And that doesnt mean bone dry either. Watering correctly is a skill. Feed it some nutes, a good veg formula about 400 ppms then add about 200 ppms of mag/epsom salt to that add microbes to that... 600ppms total. let that go for awhile.

This will take a couple of weeks or more easily to turn around, should see them get a little bit greener in a week. If everything else is on point.
Microbes...dont need alot just enough to know that you have a robust population in there working for you.

You might want to foliar feed it some mag. at about 150 ppm of mag every day for a week plus. Water , epsom salt, surfactant in a sprayer
These aint going to recover unless you get some mag in there.

are you giving them enough nitrogen?
I gave them a hit of nitrogen about a week ago

thanks for your advice
Yeah I wouldn't switch them to flower in that state. Granted they were very overwatered when I received them. They just havnt improved. I've added nitrosol for nitrogen about a week and a half ago and I thought cal/mag would be good for the magnesium but clearly it's not helping. I will try the Epsom salt and microbes. They are in 13 litre pots but only about 9 litres of soil. I've got them drinking alot faster after adding a heater and I put a dehumidifier in the tent to go with the extra drain holes and loosened soil. When I pulled them out of the pots I checked roots to make sure they were white and no funny smells aswell I was real careful not to damage anything. I watered them last 4 days ago. Today I put my finger down to knuckle deep (a little more even) was dryish so I gave them another hit of nitrogen this afternoon. I definatly wasnt adding enough nitrogen. Before today I was only putting in 50 MLS to 20 litres. I fvcked that up.

I'm using nitrosol for vege
I also put neem in soil for bugs
The light is about 650 to 700 ml away
The soil is terra professional
The bulb has only done 2 vege cycles because I use different bulb for flower.
Water source is the tap

Get rid of the heater...you only need a heater if its cold...get rid of the dehumidfier..you only need that when theres too much humidity.

they are low on mag..you need to research what mag does.

cal/mag is a supplement used for general maintenance, imo, if your low or deficient on cal you should just feed it a cal product same with the mag which would just be epsom salt. Thats what you should do but....as always for myself if im low on cal I use cal/mag and if im low on mag I use epsom salt. I do have a cal product but dont use that in flower as you want to keep the nitrogen levels low in flower.

I use cal/mag at about 2-3ml per gal....its a supplement.

I cant really find nitrosol for vege. I found nitrosol but they make different products and what I think you may be using I cant find a npk for it.

Maybe raise the light up another half a foot, when you have sick plant one of the best things to do is raise the light and slow the grow and let them recover. Or maybe not its only a 600. but the info is good to know

Soil looks legit at least its not MG.

so water ...city tap or well water tap? Your in soil so that kind of buffers it from the plant. I know in hydro city tap can mess with the plant cuz it has a bunch of crap in it. At least here it does. Is it a decent water source? Does it smell or taste funny or anything? I assume you use the water in past grows without issue ? So that probably isnt a problem. Or is it??

That leaves us with neem oil at the roots. And Im going to guess thats were the root issue is coming from. You can tell you have a root issue in the pics my first guess is over watered but whatever.

Lets break down the words neem oil, neem who cares whatever right, now oil .... oil coats things. You choked out your roots and your microbe population. Research what microbes do. Plants dont grow without it, not in dirt they wont.

How much neem did you give it and for what bugs are you applying it for?

So you need to flush the pots out. Put in a bath tub or whatever and flush it out and im talking like 20 gallons through each pot. Slowly. let it work.

Then do what I said in post 5 but instead of doing the mag first do the mag and nutes and foliar feed extra mag like I posted. Should turn around rather quickly than what your used to seeing now.

You have to have microbes though. If you cant buy them were you are at water in some worm casting at the last part of the flush and then top dress worm castings and water in the nutes and mag when you renute it after the flush. This all done at the same time. You dont flush then wait to renute them all do it at the same sitting.

Something to consider..
get a decent nute with decent ratios for growing weed,
humic acid little bit every week or two
kelp a little bit ..dont use after week two of flower
microbes a pinch once a week..I use the raw brand bloom..I use it in veg and bloom
a cal/mag for maintenance
epsom salt...weed plants are mag whores
They like more mag towards the end of flower and K
good clean water...r/o is the best for what we do. imo
and you can grow killer buds with that. And you pretty much should never have any sort of deficiency.

Yes you need a ppm meter
ph drops to check the ph before you water it in 6.2 ish area
ph up and down and all that other crap..lights environment etc.

research mag research microbes.. watch all the Harley smith videos on youtube and you will learn a lot

Learn to read a plant.

Post pics in a week or two and tag me so I know. I want to see them later on...if you do what I said to do. To the letter. Im 98.769824% sure I am right about how to bring these back Ive brought back dozens of plant cuz ive fucked up dozens of plants but you have to do what I said ..foliar feeding it and everything or else I dont really care.

a lot of variables like water source and nutes and your doing it and not myself....good luck soldier.

Nitrosol has a npk of 8 3 6
Its city tap water and is ph is 6.i believe it is overwatering but with the plants not being healthy anyway due to lack of mag.could mag be making the watering abit more of an issue?? With the neem oil I didnt fully mix it into soil it was a spray on top sort of deal just coz I didnt know the condition of bugs or anything as they came from a friend.better safe then sorry. Would you still recommend flushing through with water. Getting raw microbes isnt easy here so worm castings it is. I will take out dehumidifier but gotta leave heater otherwise temps plummet to 13 c no light and 19 c with light.

then I guees you didnt over neem it. Definitely low on the mag. Maybe just flush with about 5 gals and start with a clean slate and then add the WC nutes and epsom and still do the foliar spray. Should still come back. Probably wont need to water it again for well over a week or even close to two weeks. Just let it do its thing and leave it alone. foliar feed it though at a low ppm of mag every day or every other day. Got to get that engine back up and running.

You need to know what ppms your feeding and what the ph is before and after you add nutes to your water. before just so you know but every time before you water you want to adjust to 6.2. I like the ph drops they are more accurate than the strips. And the ppm meter ...you have to know how much your feeding it...all this could be just because you are under feeding it.

Use fabric pots my friend. I also had the same problem in my first grow using plastic pots and overwatering. I am not expert but I solved the problem. I also water the plants when the pots are complete dry that helps me to understand their consumption. Let the medium to dry 100% and water them 1L for 5L of soil. Do it in 2 phases 60% of water and after 15min give the rest of 40%. The first 60% give it slowly because when the medium is dry all the water goes dirrect to the bottom. That's from my experience.

Letting the medium dry so that the plant droops causes stress. I know they didnt say for it to droop but the plant can go from looking fine to drooping and stressed in the span of a couple of hours.

It will take 1day at least with that much moisture those plants have absorbed. There is not more safe way to fix overwatering.

It ll take longer tha a day like 10 to 14 just dont want him to go so far as they droop but yes need to fix the over watering but need to add mag first.

Then OP ....dont over water it any more 9 liters of soil would think that 3 liters of liquid would be a good watering if they spread it out and not dump it in just one spot on top of the pot

Those roots are bored now. So much water they don't need expand. A trick I do and I think lots of people doing is to water as far as possible away from plants center. Especially in veg. This way I make the plant searching for water and grow a big root system. After first weeks in flowering that stretching in completed I water the whole medium.

I don't know anyone who does this. Without complete saturation, air pockets can form in the medium, which may result in the nutrient solution simply flooding through those areas without hydrating very well. Unless just starting with a very small plant in a very large pot (where you'd water only the centre of the pot for the first couple of waterings), you want full saturation to maintain a proper watering cycle, then saturate again after each time the medium is dry.

watering is a skill that some people dont think about.
You need to water thoroughly and evenly and try to maintain the consistency of a moist cake that sways from a little bit too moist to a little bit too dry.

and yes you should water the soil totally when doing a transplant or something so you dont have dry spots that justs channel the water to the bottom. Then leave it alone till you get to that cake moistness and try and maintain that.

Yes. When it's still seedling I water in the center as the root system is small and the distance from the center becomes bigger from watering to watering. That's how I am used to watering and right now my plants drink 3-3.5L of water every 48 hours in 17L pots. Almost no run off.
