Help diagnosing a few girls please

Hi all, I am having problems with a few different plants, have tried some things but I really should ask for your guys opinions.
I grow in soil indoors under t5's and every day i lift it up by the pot to see how much water it has and decided wether to water or not, ive been using Foxfarm big grow (sometimes 4tsp/gal sometimes 2 tsp/gal) and have been adding calmg (1tsp per gal) because i thought it needed it. Here are some photos:


First is one of the bigger ones, its a dutch treat in soil. Cant remember how long I've had it but I got it fairly established, probably had it over a month.

Leaves have been developing spots and dead spots and now I noticed the leaves starting to curl way up any ideas on whats wrong with her?


I also have a smaller lsd, had her for the same amount of time as the dutch but she was a small clone when I got her. In soil and feeding with the same as the dutch.

I also have some little some little clones that are starting to have some problems as well, they are in little rockwool cubes and then i put those into soil in cups, feeding with the same nutrients as above.

Any feedback would be appreciated.

pic 1,2,3,4,5 phosphorus deficiency

LSD pic 1,2,3 nitrogen deficiency and phosphorus deficiency

Clones pic 1,2,3,4 NP and K deficiency.

N deficiency = early stage; lime green plant, mid stage; yellowing leaves at the bottom and start crawling up the plant.
P deficiency = plant leaves get grey/dark but dead spots starts in the middle of leaves, usual takes over fairly quick
K deficiency = early stage; most leaf tip are singed just at the tip barely, starts getting yellow from tips, and then gets rust spots speckled on the leaf starting at tip and travels inward

heres how you fix it. fertalize with half strength nutes(900ppm-1500ppm) every other watering, any more or any less will result in small slow growth. your doing well your plants will be 100% ok

I gotta ask whats the ppm of the water you feed them. and where are you getting your water from? if its not R/o water from a 25c dispenser or from your personal machine cal mag isnt needed

Any thoughts into topping your plants it would have reduced the overall height and made it more of a bush

I just checked the ppm with an old tester I have and it says 110 x10 so 1100? Thats with 4 tsp of grow big per gallon with 1 tsp cal mag. So should I remix some more with only 2 tsp per gallon? (and no cal mag because its just regular tap water)?

Also, is there something i should add to the nutrient mix other than grow big to fix my deficiencies? I have something called Vigoro all purpose plant food and it lists the NPK as 24-8-16 with the following on the back:
outdoor garden plants, trees shrubs, outdoor potted plants: 1tbsp/gal
Houseplants, transplants, cuttings, seedlings: 1/2 tsp/gal

Hey thanks for helping out the op as it helped me out too. Where is this leaf chart link and the seperate pages on the Deffciances ?

Roots don't like clear cups! Their great for seeing the roots put cover'em till you have roots~
4 tsp is a lot of big grow I never go over 2 one time I did with 3 and burnt'em~
I'm guessing your growing in ffof? Can't tell with it covered~
How tall are they? How tall do you want'em? I flower at 15"-18" don't wanna'em too big!
You didn't top'em? Looks like you have room for a bushier plants more buds. I top just after the 5 set of leaves. Here a pic of one of my f up's See the older growth was burnt then I flushed with 1 gallon of plain water ph'ed. It' a long story~ But see the new growth is like nothing ever happen to it I'm thinking it's going to live with no lasting effects~ I have some nice babies in ffof/rock wool too that was just topped 2 days ago their about 2.5 weeks old!

I'm not sure what soil was used, I got the Dutch and LSD from a medical club and they didn't say, I didn't ask either. I have covered some of the cups but not the ones for the clones I planted. For the clones we used a mix of soil for roses with vermiculite and some other organic potting soil, I will cover those cups tonight. I'm debating on wether to pinch the Dutch because it sits between 2 LARGE plants that I planted from soil, I pinched them at about 17" and now they have 2 huge tops and are over 30" tall. I only have 4' wide for my flower space but like 6' high of vertical space so technically it is better if they just grow taller now right? I can post pics of the big 30"ers, they had some problems back a bit bu have been good now.

So to fix the problems I need to step it down to 2 tsp per gal and no calmag and then only give them nutrient water every other feeding? I've been giving them nutrient water every time..

They usually triple in size after changing the lights to flowering!
17X3=51"+12"(pot&dirt)=63"
I not familiar with your dirt and nutes good luck!

Tripple in size?? Is that only on soil cuz the ones I just did in hydro didn't grow that much at all after putting them in flower.

Also, I should have worded my post better, I currently have them in the "flower chamber" but I have them under spare veg lights that I purchased. I can post some pics of the big 2 tonight.

another update, here's all 3 of my big ones, the one in the middle is the dutch, the other two i planted from seed. I pulled a few leaves off the big ones that were dying, very bright yellow like the regular shade of green got sucked out of them. I also see a few leaves turning dark dark green which is probably not good either.
The biggest one on the far right is 31" from the top of the pot to the top of the highest leaf tip. The middle dutch is 25" and the one in the back (on the left) that i also planted from seed is 26.5"


If there is a deficiency doesn't that mean they arent getting enough and I should feed with more nutes? The instructions to fix says to reduce my nutes? Tonight they were pretty dry since its been a few days between the last feed so I fed straight plain old tap water.

when they initially enter flowering, they stretch and they will usually double their size. i've heard of trippling in size but i haven't seen this.

and i would shoot for the most balanced diet, don't use the vigoro even if you mix it, it will only bring the N up more and the P down a lot, and K down some. K should always be the leading nute, but anything balanced is good. also i would use 3tbsp of that gro big 6-4-4 instead of 4tbsp. 3tbsp would result in 18-12-12, your plants will do better with that(less is more~)... if your K was higher your plants could handle more fertalizer and ppm. every other watering

.that vigoro stuff has the same npk as "miracle grow all purpose plant food", my advice if you do use it is too only feed half strength every other watering,

Thanks! It's starting to make sense now. I will pinch my Dutch tonight so it bushes out a bit and try to get it back to all healthy again so I can start flowering them. Should i get anything to boost the K or will lowering my nutrient strength just be ok? Also, what should I use for flowering? I know foxfarm has something for flowering but can't remember what it was called. Any suggestion to keep them healthy in flower?? Thanks again!

i would use half strength, every other watering. the most balanced diet is best for now cuz its fool proof, it will give you good results for the whole grow. any brand will do, its all the same nh3(nitrogen), P2O5(phosphorus), and k2O(potassium)

Dirtysnowball has been alot of help just following this thread. I have the same thing I believe. It hammered me starting in the 5th week except it started with little rust spots then did exactly the same thing. Very costly. Treated it wrong to start with. Thought it was cal-mag. I now understand/lesson what a K deff is and I will always ph my water indoors.

On the streatch thing, You can pretty much count on double at least. Been there done that,got a little bigger then I needed. Cut out a lot of light. Gonna flower at 15-18" this time.Just keep putting in new clones/strains off the cfl. If I keep the clippings going at the right time and size I will have more room,different strains,and faster buds instead of vegg time. I think ?

thanks man.

I agree, many thanks to dirtysnowball and mrghettogrower! Should I wait until my dutch looks better/healthier to pinch the top or should I do it now?

Can't wait to see how much I get from 4ft plants hehe
