Stickstoffüberschuss?
Habe bei meiner Auto das Problem das sie kaum in die Höhe wächst, dazu die Flecken auf einem Blatt. Ich habe aber das Gefühl das die anderen Blätter auch zu dunkel sind? Vielleicht wächst sie wegen einem Stickstoffüberschuss nicht mehr?Sollte ich erstmal ohne Dünger gießen?

Bottom leaves issue
Can someone tell me what is causing this issue and how should I fix it ? Should I just remove the “infected” leaves?

Dark purple areas on leaves — genes or environment/feeding problem?
What the heck is this? Is it just purple genes or a stress/deficiency or a combination of multiple factors? I have checked three visual cannabis plant health guides, and did not find a single issue which looks like this. Maybe a combination of 2 factors, but I'm not convinced 😐

Why are my leaves getting brown yellow?
My leaves are getting brown/yellow, I saw online that it's a bad sign but I don't understand if it's under watering, overfeeding, underfeeding, light burn ecc? Thank you so much for the help first time grower.

Emerging Issues - Week 9
At the beginning of the week, I noticed the tips of the leaves drying out. Now, one out of the four plants has completely yellow leaves. Could it be due to the increased Biobizz Bloom dosage? For more information, please check my journal. Regards.

Leaves looking f’d?
What’s happening with these leaves? It started last week and has spread. Only the leaves in the middle under the light. Week five of flower. Was using the same nutes and strengths since flowering started at 6ph. Upped the strength this week to see if it would fix and it got worse

Brown spots new leaves - flowering
Brown spots on the canopy and leaves are less greener. I suspect it is Calcium deficiency caused by a acid Ph (my Ph meter was not calibrated). I have flushed it and fed it normally 5 days after the first signals. Is it really Calcium def or another thing I'm missing?

Fertilizer burn or something else?
Hey fam. Plant seemed fine a few days ago besides a mag deficiency. Decided to foliar spray cal mag at half strength a few times. Now there are brown patches and leaves/stems are curling down like they’ve been overwatered. Too much cal mag? Burn? Something else? Thanks!
