What is wrong with my seedling?

Your stem is purple, so it’s too cold, and the light is too powerful for the reaction to occur in the cold so it hurts the leaves. Increase temp. Wow looks like you fixed it. What was it? More N?

Switched to gen hydro trio 3 part feeding plan with calmag.. and it all goes away. The temp now is somewhere 24c-25c should I increase temp? If I increase temp should I increase the light intensity currently its on 350-400par

Time to mention your lights ? led? Some say to run the temps in LED higher, 28 they say. But keep in mind humidity. I think the plants look fine. Maybe don’t change anything. But try letting it get hotter now. Then cool down in flower.

some colas are very near the light. But doesnt show any heat stress in the leaves. maybe a little browning on the tips of the big fan leaves. peak temp is 28c .. should i defoliate fan leaves for further light penetration? this grow has 8 main colas

The plant has tripled in size during the transition. I was worried it might outgrown the grow space this is 2x2 btw.
