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

What could be causing this?I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far.
I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout.
Anything else it could be??

Any ideas on my lower leaves cupping? I'm thinking a root issue from overwatering. I last watered 6/11 and this started showing on 6/13 and has progressed. Soil is still moist and fungus gnats popped out of nowhere this week as well. Have SNS 203 for next wateringWeek 3

Slight lightburn?First pair leaves on left plant turn slightly lighter, first sign of yellowing a bit. Also I think they are a bit in a V/praying shape.
2 full weeks old under 75% of 200W leds about +-45cm. Should I dim them a bit more/hang higher?
Other suggestions maybe?
