I recommend the Amazing Dr. Zymes. It's a one-spray-kills-all fungicide/pesticide and I can't recommend it enough. You can even use it in flower or right before you harvest, which I think is great. Pests and powdery mildew don't stop attacking your plants just because they are flowering. To answer your question: Something is definitely Chomping on your plant. BT spray is also a great option to kill pests, but it only takes care of bugs that chew on your plants. So, keep that in mind. If you don't have any Dr. Zymes, here's a link for some free samples and a cool pin. You just have to pay shipping. www.doctorzymes.com/wizard I hope this helps.

You've got something having lunch at your expense... grab yourself some BT (bacilius thuriengiensis) and spray just before lights out... whatever is chewing on them will take one bite and decide to have lunch elsewhere... so they'll go off and die elsewhere! You'll probably have to spray at least once weekly as a preventative measure - or after a rain (it looks like you're doing an outdoor grow)... Good luck!

Critters, various kinds of. Outdoors happens but are insignificant damages and until remain random bites plant don't care a fuck about these (expecially if in plain soil). Spray something organic to control them. Healty plant, keep it up

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?

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 😐
