Phosphorus def??

not enough light is what i would say. lower lights so they almost touching without burning.

Are you over watering? U need to only water those every 3 days. dig down with your finger to see how moist it is. Are you checking your ph with a ph kit? How warm is the environment? do u have a fan on them? what soil is that?

HMM i think i got the same thing man but am on day 29 right now and i have a brown spot on my bottom leaf that is going yellow as well seems to be going upward i though it migth have been root bond so i transplanted to bigger pots check out my journal to see if its the same thing my plant have alot more leaves then yours do tho.

yes i use the three inch method to test when i need to water and water enough so that 10 percent runs out the bottom....ferts im using for sick one is dr. hornbys iguana grow juice. lighting is as good as it is going to get for now but i do always keep them as close as possible without burning.. ph is fine b4 and after water leeches thru. so technically feed her more? or shuld i just flush her and try to start over on her? any help is appreciated as this is my first problem ive had...my lady in flower looks good she had same symptoms as seedling but grew out of it.

and yes hazy she is very stunted i think but i dont really have much to go on since i flowered my other female at 4 nodes.

another thing should i be adding noots every single time i water or maybe once every 3 waterings...thx

definately not every time!! That will cause nute burn!

I only nute once a week after they 3 weeks old

OK bro i got great news for u and me my plants look so much better now i came home from work thi king they would look worse but!!! they look so good now hehe all mine needed was a biggger pot i think they were getting root bond.. i dont know if you have the same problem but if ur plants are yellowing from the bottom up i would transplant them and gently work out the roots. thats what i did.

Ok guys I heres an update. I figured out the problem!! I waited a few days and the plants would not get better after the flush at all. I ended up testing the pH of my drainage water to find out it was way over 6.8 even though the water I was giving it had a pH of 6.8. This was very confusing to me until I realized that vinegar was doing this. I did a test where I mixed vinegar with water and got a pH of 6.8. I left that water out for 2 days and tested the pH again and it was up to 9. Lesson learned, FUCK VINEGAR! haha. It's too unstable. I went out and bought some pH down for $16 and I have transplanted the plants in bigger pots today. I'll keep yall updated on how the plants do with these adjustments.

ya i transplanted my more sickly plant and been testing ph it all normal. hopefully the transplant will help

Good job bro hope your grow goes smooth from now on.

How is everything going man??

Problem has been solved. It was the vinegar. My plants are growing at an exponential rate compared to before. Ive seen a new node every day.

good to hear so man good luck

same here basically pruned and transplanted and man did she take off!!! im so excited now ive got nodes everywhere and my hps gets here today! question is to flower or not to flower...hmmmmmmm toke one peace
