Brown Edges on Leaf. Bit of yellow and purple.

Chow_13started grow question 4y ago

What could be causing this? And how do I fix it with GH flora series. It is only showing up on one bud site. But I believe its getting worse. I also noticed other leaves all of the jagged edges are slightly curled up

Looks like you have a potassium deficiency or lockout, this causes the edges of leaves to appear burned like the ones in your photos.

So how would I treat it. When this started I was doing a ratio of 1 Gro 2 Micro 3 Bloom. But after I noticed this I did a reservoir change and changed the ratio to 1Micro 2 Bloom. Not using grow at all.

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?

Are those nutrient defficiencies? Which ones?A plant had interveinal chlorosis on new leaves and then proceeded to show brown patches between veins on middle leaves. Another has coppery brown spots on leaf edges on the middle of the plant. Both were rootbound in living soil (peat/perlite/hummus + ammendments).

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 😐
