Hey friend, it looks like Nitrogen and Phosphorus deficiencies to me.But on the other hand, Plant is using the energy from leaves to make your buds fatten as you are using P/K booster.So it seems fine to me.Happy Growing... ✌️

How are they looking? Think she had light stress last week so light is much higher now
Hey everyone, my Dark Devil Auto has has dark green leaves for weeks now and is now showing purple under her leaves. Just wanted to know people thoughts? I’m only giving 450ppm to all plants with GHE FloraTrio in line with their feed chart and some bent tips due to small tent!

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 😐

Some sort of deficiency?
I'm thinking it's lacking phosphorus, but this is a first for me. I gave bio nutrients yesterday, which also contain phosphorus. I've read that bio nutrients need a bit of time to become available to the plant.... Any other feedback is also much appreciated

Problema con mi Runtz Muffin
Good morning, I have a problem with my leaves (I posted photos so you can see). I've seen that it could be a phosphorus deficiency. But it could also be a calcium and magnesium issue. Could someone help me with this? What should I do? Should I add a PK 13-14?

Why is the new growth turning purple?
Is a night time temp of 15degrees the cause? I can't keep it up without making it too hot, or could this just be a phosphorus def.? I fed her well yesterday and yet to see any difference, as far as I can see this isn't typical for the strain

Is this turning purple from temp change
So it looks like what I thought was a brown spot (under the grow light), appears to be purple when I pulled it out to get a better look and stake it down. I did switch the light to something cooler, could this be from temp dropping. Not worried yet, just curious. Thanks

Phosphorus deficiency?
Does this look like early signs of a phosphorus deficiency? I just gave her her first feeding of p/k boost last night. Should I have started that earlier?

Why is one of my plants turning purple at the top?
One of my plants is starting to turn purple at the top, both leaves and the bud itself(As shown in photos 3, 5, and 6 for week 11). Could this possibly be bud rot or something I should be worrying about?
