I'm thinking that there is a problem with yellow leaves.
Sun_Sweeds145started grow question 2 years ago
I felt that the newly sprouted leaves just began to turn green and yellow. Is it a nutrient deficiency or ph? Cause , I only feed her with water and nutrient-dense water.😓

I don't see an issue at this time, looks healthy to me.
New growth will take a day to brighten up or get greener, normal growing patterns IMO.
Good Luck!

Transplant ASAP, they will be root bound by now and clear cups are a no-no for healthy root growth too.
There will be absolutely no nutrition left at all in those tiny cups/pots.

Nitrogen toxicity? Deficiency? Something else? Stumped!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.a year ago

Older leaves are yellowing, brown/red rusty spots, dying tissue, red stems.Older leaves have brown/red rusty spots and looks like dying tissue in between the veins.
Burnt tips, and yellowing leaves.
The soil was really dry and my PH meter was 0.4 too high.
I gave each plant 3L of water with EC: 0.0 PH: 6.4 to check runoff.
Runoff was PH: 6.1 EC: 0.8a year ago
