That's just old N tox leafs, degradation is all buddy. But to be safe. Check underneath leafs for eggs and of course you'll see webs. Good luck pal

Burnt? PH lock-out? too much Cal-mag??
What do you think is wrong with this plant? All the other plants surrounding her are fine so I'm not sure what went wrong with this one. I thought it was cal-mag deficiency at first so I doubled cal-mag when feeding but it only proceeded to get worse. The buds look fine tho 👍😳

What is causing my leaves to turn dark and dry?
I'm growing 3 Gelato #33 plants in a DWC 5 G bucket setup. Same conditions for all 3 plants, but one of them is experiencing dark spots on the leaves and now they are beginning to shrivel up and dry out. The newer growth looks okay, but might not last long. What can I do ?

Bud rot? Mold?
My plant is a bit problematic ("quick one" Auto from RQS, outdoor balcony grow). I'm a bit worried that I have to throw it out, therefore I would like to ask for your expert opinion. :) 1. Is the "brown stuff" on the top bud "bud-rot"? 2. Are the "more intense white spots" mold?

Brown leaves - what am I doing wrong, folks?
They look yellow in the photo, under 250W of blue light, but they are brown. This starts at the tips of the large lower leaves and spreads quickly to the whole leaf. Also modest edge curl. What am I doing wrong here, folks?

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?

Fungus or deficiency?
I have these gals growing outdoors and have a few leaves that look like this. Appeared after multiple heavy rain days. Applied nutrients yesterday so I still need to wait for the results. Is this a sign of fungus or deficiency?

Brown little spots on leaves
Hi, I went on vacation for 4 days, the ec went from 1.2 to 0.5 and many small dots appeared on a lot of leaves. Do you think it's due to that ? The ph went from 6.2 to 6.4 but I don't think that's it... Thank you for your answer :D Peace
