Spots and yellowing
marleyjane
started grow question 5y ago
Hi Gurus, Just spotted some brown spots and a bit of yellowing on a couple of leaves. I’m 5 weeks into flower and just noticed them. Doesn’t seem to be fungus as it doesn’t rub off. Any ideas what it could be?

Brown spots on top leaves - nutrients, light or something else?
She went into flower, now stretching. Set light to 100%, added Bio-Bizz Top-Max and Bio-Bloom (1ml/L each). 3 days later brown spots appeared on top fan leaves, very few also on lower fan leaves. I suspect this could be light burn or nutrient related. Any ideas? Pls help

Bei der Pflanze sterben die Blätter
What could be the cause? We checked the EC and pH values and everything is fine. Other than the sand, we haven't done anything differently. Does anyone have an idea? It started around week 6 and is getting worse.

Yellowing on leaves tips. Should I start feeding her?
Some yellowing appeared on the leaves this last day. Temps and humidity are controlled and ok. I haven't been feeding her, she has been growing on light mix for the past 25 days. Im thinking its time to start applying some nutes. Or could be something else? Thanks!

Nitrogen toxicity mid-flower
So I overfed during veg and now my plant has nitrogen toxicity. Besides making leaves super dark, crunchy, and yellow it has also made my buds pistils curl and brown way too early. I’ve been flushing often with water. Is she a lost cause or should I ride it out for 4 more weeks?

Wilting and yellowing leaves after vinegar water solution
I sprayed a mixture of 1/4 spirit vinegar + 3/4 water under the leaves to get rid of aphids (which may or may not have been the problem) earlier today. Now checking on her, I see yellowing of several leaves and wilting of others, which has me worried... normal, or a problem? 😳
