Ingiallimento fogliare
Trekkystarted grow question 4 years ago
Salve a tutti, sono nuovo membro del team, ho cominciato da 1 mese una coltura indoor. Da 2 settimane mi porto indietro un ingiallimento strano delle prime foglie di una autofiorente ma non capisco il problema dato che utilizzo un substrato concimato e scarti di caffè per azoto

Reduce nutes for a bit, may be lockout. Stop foliar spraying leaves, or dry them off when anything drips on them. they are solar panels. roots absorb water and nutrients, not leaves. Those products are made to pry you from your money. (excluding pesticides when you have a pest, not preventative)
you don't fertilize? the soil will only provide enough for only so long without it. if it worsens, go ahead and provide more.. N is a good bet.
if you think you've bombed it with N lately, back off for a bit and see how it reacts.

Leaf Diagnosis NeededI need help. Leaves are turning yellow at top of plant only. And only on American Pie. Not Northern Lights. I am using a Sonlipo SPC2500. Bloom mode. Is it possible to have lower ppfd levels and still get light burn? Thanks in advance.

Little seedling having a hard timrSo guys;
I'm worried about this seedling. She's having trouble on keeping up with her sisters. I noticed a yelow color on their tinny tips 🤔
Cotiledons got brown pretty quickly too.
She took longer to "open" the cotiledons after popping from the soil.
Should I do something?? 🙏

Weak yellowing leavesNot every single time but quite often my plants are turning yellow in the middle of flowering. It starts from bottom and follows to top. I can basically “take off” leaves off stem and the upper ones getting dry and brittle. I’m also quite sure the ph level is correct. Any guess?

Calcium / PH issues? Did I take the correct steps?Am I on the right track to remedy my plant's issues? Seems like calcium deficiency to me. Soil test comes in at just under 6.5, my reservoir water going in is 7.3ph, in case its actually a lack of calcium and not the PH i've top dressed gypsum (and epsom salts).
