answered grow question 4y ago
Not septoria but burning from severe nitrogen toxicity would be my diagnosis. Feeding too much or too often (or both). Not watering to run off each time can accelerate the problem.

Possible toxicity or deficiency?
I saw this on one of my bottom leaves this morning. Hopefully someone can give insight of what it might be. I'm concerned that it is phosphorous deficiency. I didn't notice it a day ago, but I wasn't looking closely. 2 days ago I watered her (540 mL, 1/4 tsp nutrients). Thoughts?

problems with clones!
Friends, tell me what's wrong with the plant! I don't understand it's under-feeding or over-feeding! At first I thought it was a cal-mag deficiency, then I saw a purple stem and thought it was a phosphorus deficiency! Now I don't know what it is anymore! at the very beginning it

Carences ?
Les veines des feuilles des Txerri Bilbo Haze deviennent légèrement bleues, est-ce une carence de phosphore ? Les feuilles de la Master Kush s'éclaircissent sur les bords, est-ce bien un manque d'oligo-éléments ?

Light green leaves in color and burnt tips. Some leaves have brown spots.
Hi guys, can you please help me diagnose the issue. The plants are in BioBizz All-Mix soil. Treated with Bio Grow, Bio Bloom and Top Max from BioBizz. Also BioBizz Cal-Mag in the past week and 1ml of B52 (twice). A week ago I flushed and initially they were looking good.

Deficiency or toxicity?
Hello i'm not sure what's going on, is this toxicity or deficiency? She loojs happy overall but new leaves have weird color, curled down tips, some of em are yellow and some are brow - burned.. maybe it's because she's transforming into bloom phase, PH 6.2 but runoff is PH 7.1.

Im getting what looks like a Nitrogen deficency but I have put nutrients on my plants and still the same. What other thing can cause this? PH? All strains are 4 to 5 weeks old and already flowering. Yellowing started to show very early, since week 3 and leaves fall off.

Overwatered cubes in hydro? Too close to the sun? or effect of having add
Hi All, I have issues with my first hydro grow - i effed up. I think i was too slow in the transfer over in the tank. Light is 200 PPFD, EC at 0.6, and barely added any nutes. Did i manage to overwater some of these plants by having them too close to the net pot?
