started grow question 2y ago
Why is my Amnesia XXL Auto, as shown in the pictures, developing purple and yellow leaves? It has been fertilized exactly the same as my other two plants, which look great.

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 😐

For a couple weeks there has been some redness in the stalk which I’ve thought nothing of. However, today the edges of some smaller sugar leaves have started to turn purple. Temperature is staying as noted above, should I be concerned?

Leaves with purple edges normal?
Leaves are now changing to purple edges and know that some strains just have different coloured leaves, but this has just happened later on now she's under the light inside and couldnt find any pics of super skunk with purple-ish like leaves. Normal? Stupid question probably!

Autoflower Selective Harvest?
Should I do a selective harvest on an autoflower? My plant overall is pretty uniform in height outside the main. Is it safe to harvest so that I can drop my light to give the rest of the plant the light it needs to finish strong?

2 part question about harvest and flushing. I read that if most leaves around buds are turning color (purple in my case) you need to harvest soon before plant dies, is that accurate? If so my runoff is still the color of an ale after 3 weeks of flushing, is that normal or bad?

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.

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!
