If you had leaves wet under light, possibly lightburn.

I'd guess a calcium and/or magnesium deficiency

Yellow discoloration again
I'm annoyed by having to post another question but oh well. Yesterday evening I increased the PAR from 370 to 400 in center. This morning the top fan leaves were pointing straight up and so I raised the lights a little. I later looked and saw discoloration. Light burn?

You are a SATIVA North Shore Maui! You grow tall like the sky! Strong like mountain! You are not descended from short plant!
Currently overthinking this plant's development. Pep talk not working. It is a sativa but the shortest plant in my garden. Maybe just needs a trim? The yellow is a concern too. I haven't dealt with a plant this bushy before so not sure if it needs help or not.

Day 4, after emerging. Is this coloration on the cotyledons okay?
Humidity is 55 - 70, temp is around 20-24c, 50w full spec led It's my first time, and i think i have been watering it too much I also fed it 2-0-0 npk water with 4ml per liter and I since learned it's not okay. Will it recover? Is this too little grow for day 4?
