Leaf tips curling up are an indication of LED burn. I’d suggest trying to raise your LED lights.

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?

PPFD Management -- Am I doing this right? :) (See fan leaf photos for curling)
TS1000 (150W x 2), set to 75% at 12-14". "Photone" app (yes, not as good as a PAR reader) reads 580-700 PPFD, so I sense these girls aren't getting as much light as they could. I've read that pushing 900 PPFD is desired (CO2 bags);fan leaves curled. How should I think about this?

Blattränder trocken
Hi everyone. I'm in the 5th week of flowering and have had slightly curled leaf edges for about 2 weeks, and the newer leaves look a bit dry. I haven't changed anything except for maybe a bit too much fertilizer. Could that be the reason? I appreciate any tips!

Clawing/Yellowing? (def not over watering)
Anyone want to take a guess at what's going on with the clawing/yellowing? Very highly doubt it's over watering. It's slowly been showing more signs of it the less I water and I'm pretty heavy on perlite. Also using the lower recommended amount on the nutes.

Light Intensity Question
Pretty sure that it was light related. I didn't know that too much light was a thing. Can someone tell me about it? I'm not talking about how much light, more on the intensity factor and how it affects plants. Please?
