It's just anthocyanins in your plant. Some genetics go purple no matter what, but cold can bring it out of a lot of plants. Evening temps dropping towards the end is usually the cause and nothing to worry about.

These three girls are all wilting and/or barely growing. I'd say over-watering except I've only been giving maybe a quart then waiting till the soil dries a little bit. Not too much tho. Could it be a nutrient problem already?

What to do? → BF Runtz Auto - Day 42 - RH70, 80F in BioBizz Light Soil On my last post, I was advised I have N tox, so I watered w/o BioGrow, just BioBloom and it's gotten much worse. The runoff EC was 1.5 (watered with 0.8, runoff pH was okay), so I’m guessing it's salt buildup. I plan to flush when this watering dries out—any thoughts?

Seeing some top bud leaf discoloration Starting to see small dark/black discolorations on the leaves. Since I don't know the genetics, I can't tell if it's prone to dark leaves. Could it be signs of anything else? Note: Started watering only using TopMax and ActiVera because of some possible Nitrogen toxicity
