Yellowing and low growth- cant tell exactly why.

I grow in soil.
I use the terra aquatica (general hydro) organic grow and bloom fertilizers with bloom booster and root booster. I also supplemented with canna rhizotonic, fulvic acid etc.
These are questionable quality auto granddaddy purples and auto ak47s.
We had no problem at first. One of our plants was growing way faster and started showing pistils way ahead of other plants and it was also the one to first show the problems. Leaves started going yellow, not in little spots as in leaf seporia ( not sure if spelled right) and not starting necessarily from the tips of leaves or covering the entire sides, just randomly regional. Those yellow areas grow on the leaf and eventually I prune it. The ahead plant that showed the first problems, I had to prune so badly that it is very overdefoliated. Now that the other plants are showing problems, I am starting to panic. We have had some days where the temperature reached 32 C but mostly we try to keep the AC on and take it down as soon as we realized, the problem is the ac of our rented house turns itself off automatically sometimes and its hot weather these days. We used straight tap water without dechlorinating it at first but we have fixed that long ago. And for the last 3 weeks I have been phing my nutrient water to 6.6, but before that I am sure we were giving either low or high ph water. I will attach some photos, would be great if you could help. I water once the pot isnt necessarily heavy anomre and my finger feels dry when i poke the soil. I put the amount of nutrients as directed on terra aquatica (GH) products. I have tried straight watering, low does nutrient and full does nutrient, nothing seems to change. I use 2 mars hydro tsl2000 s in a 4x4 on %80 at 50 cm to make sure its not light burn. The other plants are just showing a few problem leaves but the first plant is in serious trouble. I am suspecting of ph and mean to take it to the bathtub and flushing it with 6.6 ph water, using water 3 times the volume of soil. Is that wise?
Let me add that the yellowing seems to start at the first days of preflowering and it is not on new growth, only existing lower or middle height leaves.

Bump, please, they are constantly getting worse and idk what to do

They look over stressed due to roughouse LST. When you train plants like this they get stressed.
Reduce watering almost stop watering for now. Do you have an osc fan going in there 24/7 ?

How is the ventilation ?

I might have overdone the lst, this is my first grow and we werent meant to receive auto seeds. Shall I Untie them? I have stopped lsting 8 days ago. Right now the grow is in its 39 th day. Why reduce watering? I dont water before the soil is dry to my finger, light and the leaves droop as I will add the attachment. Just asking to learn why. I have a small fan blowing to one side but it does not oscillate. Another main fan is sucking out of the tent through a carbon filter constantly, the tent is 4x4 and

this fan, the 380 m3 model.

I flushed the far ahead plant with 6.5 ph water without nutrients thoroughly. Afterwards, I fed it juuust a little bit of water with 1/3 the regular dosage of nutrients. It revigorated and all the leaves seem much livelier but I expect that it will take a while for the yellowing to stop completely.


This is the current situation.





This is the ahead plant which was ahead of others and flowered first and also started yellowing worst and is in the most critical situation. This is its lively good status after the flush.







When they dry, some of the plants go like this and this is when I know I must water. I dont always wait for them to droop this much. ( Is wilt the correct word instead?)




I am now going to show some of the other yellowing starting on the other pots, since they are similar yet I might be missing something and they might be different. They are all old to middle old leaves, not the new growth.

Plant no 4





Plant no 1



Plant no 2





Also, if you have any suggestions about anything at all, would be much appreciated.

Do I have way too many tops for auto plants? all I did was lst. Should I take out the smaller ones or let them stay?

The soil is too low in the pot, I am aware and that was not intentional. I will fill the pots higher next time.

Bump. I am new to the forum and dont really know the appropriate period of time a thread should be bumped, warn me if it is too early.

I am having I believe the exact same issue with my 1st grow. I couldn't have explained it any better myself
I am in 3 gallon fabric pots FFOF and 25% extra perlite, 2x2 tent 4" ventilation system with carbon filter, 1 small non oscillating fan pointed at wall and 1 Vicodin oscillating tent fan
600w vander life led 16 inches from plant 18/6
Water with 6.5ph'd water about every three days 1qt to 1\2 gallon
PPMed to 550
Plant is 19 days old

These look super over watered, almost every plant looks over watered. How much are you watering and how often? The yellowing doesn’t really go away, they usually just become blended in with new growth, I tend to remove them once it has bounced back.

Are you using a calcium supplement?

20l pots, 15l full with soil, I water approx 1.2 litres of water approx every 3 days. I add terra aquatica (general hydroponics) organic bloom. It says 2ml/l but since I feed every watering every 3 days, ı put 1.25 ml per litre. What made you think these were overwatered, so I can tell too. Also, one of these plants is severely underwatered (the wilted one). Everytime I water thr top 5 cm is dry, it is light and the photo I posted which I called drooping or wilting seems requiring watering to me. So because it didnt intuitively make sense to me, I would love to learn. Thank you .

I put 1ml of terra aquatica cal mag per litre everytime I feed. The water isnt very soft either.

I wasn't getting runoff so I didn't think I was watering too much but maybe
please help first time grower

Was also adred 4ML/gal cal mag plus

Bump

This is what they look like right now. I flushed all of them as a last resort and they all look much healthier, The further damaging seem to has stopped. The ones on the left have been flushed just now, so they do not have yet the vigor of the previous flushed ones on the right. I am guessing the ph was fked up. I normally should put 2ml/l of organic bloom of terra aquatica (ghe). Instead after flushing I fed them with a little bit of grow for once, and I will continue with only bloom from now on, because some were nitrogen deficient even before the flush. I fed 0.5 grow 1.5 bloom and 4 ml bloom booster. I am not sure whether to feed nutrients every 3 days with watering or once every 2 waterings or half dose every watering. They are not chemical ferts.




They are mostly ok now but there are some different problems I think.
Now I will post the plants seperately. They have slightly different problems I will further elaborate.


Plant 5




This is the ahead plant that had the problems first and the one who took the biggest hit. She recovered immensely after the flushing and all the new increased growth looks healthy. 3 or 4 big fan leaves which had already started yellowing before the flush are like this right now.




Plant 2







This one was flushed today so this is the before rejuvenation photo. This one has 4 big fan leaves like this. If it were only yellowing I would say its because of the nitrogen being carried to new growth but is the drying up normal? Will this continue to new growth after the flush today?




Plant 4







Dont mind the cut leaf on the 2nd photo, unintentional. What I want you to see is the yellowings and brownings at the tips. Same plant. This was the plant with darkest colors and least yellowing anywhere on the plant, nearly none. Because dark color meant excess nitrogen and this plant had no yellowing at all, I am further suspicious that the problem was a nitrogen deficiency caused by most probs ph problems. Still no yellow leaves but the tips are like this. Let me also say that the tips are the same on other plants at varying levels.



Plant 3







This plant looks very much like plant 2 right now and how plant 5 (the ahead one) was right before it was flushed. But unlike the plant 5 which was flushed 4 days ago and recovered immensely, this was flushed yesterday. The amount of yellow leaves with brown dry parts is 4. Like all the other ones this has yellowing at the tips too. The cupping is non-existent on the new growth, but shall I be worried.

Bump, please help
