Buds looking good but what is happening with the leafs?

[TurnUp]

Skunk AUTO
Entering second week into flowering
soil mixed with perlite
under 250W hps
leafs are a different collor and i don't know if is underwater or overwater and what lack of nutrient the plant have.
My soil ph meter show between 7 and 8 and i don't know if that shit works....

Are you using any nutes? Based on the pic it could be a early potassium deficiency or nute burn just depends on certain factore but in general autos are easy to burn

 

[*BUDS]

Its nute burn, flush well then reduce the feed by 20%.

2nd week flowering is a good time to flush imo. Flush real good and let them rest for 3-7 days (depending on how much they drink) and then balance your watersolutions to 6.5. 7-8 is a little too high

i've flushed it 3 days before the photos so it's a k deficency. I use nutrients and in flowering i use 2-2-4 but as i said the plant was flushed and didn't have any nutes in the soil. i've added nutes yesterday....10mL/1 L

Looks more like a pded with those pics, i have to agree with jpizzle. And 10ml/l is recommended? Varies from brand to brand and lady to lady.

I use a product from CANNA
Terra Flores

Are you using a PH probe? if so, they are not very accurate as you have found out. I messed with one for a while and had issue after issue. I purchased a soil test kit at my local everything store for a few bucks. Turned out my meter was not correct and my soil ph was fine. It did tell me what was abundant or weak in the NPK department and I adjusted my soil mix for that. I no longer have the issue you are having. I tried using the Canna line of nutes and it was a bit to much for me to grasp. Organic has been the best thing I have done so far! Water only with a tea near the end of flowering.

Can't really understand this :Water only with a tea near the end of flowering

I grow organically... In other words, my soil contains everything the plants need. Clear water right out of the faucet (ph 7.14 ppm 180) all the way to day 47 of flower before they start to fade. Day 40 I start watering with teas made with compost, manure and molasses every other watering. I still get some fade near the end but I don't have deficiencies any more. I just added Dr. Earths Flower Girl 4-10-7 to my tea regime so time will tell if it was a good choice.

I still have a crap load of Canna nutes and a bottle of Cal-Mag collecting dust!

Second set of pictures are showing a Nitrogen Deficiency and Magnesium for sure. 2-2-4 or 1-1-2 is not a good ration for cannabis. You need a bit more Nitrogen, More like a 3-1-2 ratio. You could amend your 2-2-4 with some fish emulsion which is usually like 5-1-1.

I have another nutrient with 6-3-6

I am interested in you re method...can you tell me more?

Piggybacking on the original post that your above comment refers to:

soil mix: 40% FFOF, 40% Happy Frog, 15% Perlite, and the remaining 5% a mix of blood meal, bone meal, worm castings and dolomite lime. That will get you through 30-40 days with only ph'd water, no nutes. After that the only thing my plants get is teas ( as mentioned in the original reply ) with possibly the addition of some 0-0-8 towards the end. I also make a banana tea to use towards the end ( take a banana, peel it, eat the banana, put the peel in a small pot with some water, boil for 9-13 minutes, add to your ph'd water and feed to your plants.

I do have some leftover General Organic nutes that I occassionally feed with but it's mostly just because I'm trying to use up them up and get them out of my house.

Just FYI, the above works great for 12/12 from seed, if you veg you would need to adjust some.

That last pic definetly shows lack of N. Why dont you mix in some bloodmeal and add a little calmag. Effect takes a little time though so might wanna consider some liquid N adds. Also keep in mind the def can be caused by lockout if your ph is too far off .

Also npk should look like 312 for veg and 123 for flowering imo. I guess its different for most people but i always get my plants across the finishline even though i have a lot of troubles along the way.

No hermies yet though

I think my ph is far off but i don't really know how to low the soil ph. I've tried only flushing with ph'd water and that's cause a friend told me that this is the way to change soil's ph...

 

[sacro]

Partally correct. The problem is always how much to adjust. Even if your soil is 8+ you dont wanna water with acid Always take it slowly and stay in control. Do not jump more than one full number at a time. Say youre at 8, water with 7 for a week. Then measure and see if its lowered. Then water with 6 and check again a week later. You want 6.5 for soil. Most nutes are acidic so if your water is lower than 7 your soil ph will most likely reach down intp the 4s

Remember, measure PH after adding nutes!

You had over-fert in the beginning. The leaves are too dark and glossy to not have over-fert. In your second set you can see the nitrogen deficiency, possible K deficiency with the necrotic spotting. The tip burn from the over-fert is still present. If I had that problem I would spray water to leach the leaves (3xday or whaev), and flush the pots. Get some botanicare fert and feed 500 ppm at 6.2. - but do this feeding after you see the glossy green lighten up in color.

As Greenlikemoney said.....


I myself do not have a specific formula for my soil. Hand full of this and a pinch of that. I do however have a semi large amendment stash.

I re-use my soil after I harvest after adding amendments and letting it cook for at least a month. It just keeps getting better and better as time goes by. I would suggest reading in the organic section a bit. Just don't get overwhelmed...

I also agree with Chex1111.... about the over fert in the beginning and the starving towards the end. Been there done that!

Annnnd... I am one of those "Toilets are for flushing" guys...... I would never rinse out my soil and any extra run off is used as a tea to moisten my cooking soil.
