Nitrogen toxicity? Deficiency? Something else? Stumped!
Lemme_Adamstarted grow question 5 months ago
I don't get it. Is this N toxicity? Serrated upturned edges, clawing, slow growth. But how? FFHF 75% FFOF 25%. Just Cal-Mag water. No food. NLS in bottom 3rd of pot. Not wind burn. Not too hot/dry at all. N deficiency? Yellow leaves on first bottom two only. I'm stumped.

Yes, this is N toxicity. You got nutrient waste salts inside your soil. You need to flush them out. And in the future water till runoff to prevent this problem for the rest of the grow.
For the flush you give the pot volume in water with pH 6.2 without nutrients.
For the runoff you want 10% from the water that you give to drain from the bottom of the pot.

I would say it is in the beginning of it yes. I can see some N clawing on some of the upper growth in the mature leaves, When the tips point down are the leaf if dark green its a sure sign. Just ease up on the N and it will correct its self on the new growth. Older leaves that are dark green will become more brittle and may fade in vigour........ I do not see your feeds listed in the diary, but if they are the same as your last diary then Fox Farms feeds them on the heavy side, Best to use a TSD Pen or equivalent to determine if they are getting the right concentration. Also good to note with liquid nutrients its good to get min 10% runoff of the pots volume to prevent a buildup that could cause more issues down the road..........Best Of Luck!

What have I done wrong and right?I'd love some critical looks at my plants, there are two in this grow. With only a few weeks left, I don't think there is much I can do to really improve things. But, please look at my pictures and tell me what you see wrong and what I should have caught. THANKS! 🙏4 years ago

Is this heat light burn? HPS 600w at 20cmIs this light heat burn?? These are all buds at the top of the canopy and they are the ones nearer to the lights. I have 2x600w HPS, one with a cooltube and the other just with the wing. The possibly burnt buds are the ones under the wing (just 20 cm).
