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

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?

Leaf Troubles: Nutrient Overload or Calcium/Magnesium Deficiency?
What’s happening with these leaves? The tips are curling up, and the DLI is below 45. I’m unsure if I’m overfeeding nutrients or if there’s a calcium and magnesium deficiency. What do you think the issue is? Please help me, I need to feed in a few hours.

This margin curl appears to have spread from one plant to 2 of the other 3. So I assumed not pH, not lockout, not nutrient based. Roots all great. I've culled the 3 and there is 1 survivor doing well but what was this? In the diary I mention using Temprid FX, Neem, Spinosad.
