Doesn't look normal for the strain you're growing, so it's probably because of cold nights.. cold can make the plant switch out the chlorophyll for Anthocyanins.. - It's not really a bad thing, as it makes your plant capable of absorbing a larger spectrum from the sun, tho at a diminished capacity.

Leaves dying week 6 flower Hey growers, I'm at the week 6 of flower, and leaves are dying in some specific spots. Runoff ph was checked, 6.4. Feeding 4ml/L bb top-max & bloom. Bio-Grow was cut off after dark leaves, clawing & burned tips. Does someone know the cause? And how big a deal is it? Thanks!

Purple leaves getting worse!?So I started getting light purple/yellowing last week, after my last grow question, I landed on potassium deficiency. I gave a healthy dose (2 tbsp in a half gallon of spring water) of Fox farms big bloom (0-.05-.07), within the last 48 hrs and the purple looks worse? Any ideas?

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 the leafs on my plants getting dark green instead of a light green? Is it because of the strain or nutrient lockout (nitrogen toxicity, too much potassium, too much phosphorus?) or perhaps not watering enough?

Dark tips it seems to me that the tips of the leaves have a very dark color, it looks like an excess of nitrogen but in three weeks I have never fertilized and the only additions to my biobizz light mix are a sprinkling of guano kalong and 10% of worm humus biobizz.
