Why are my plants leaves so bright green/yellow?Wondering if anyone knows why the plants might be looking as light green as they are? We are running a purely organic grow and have not added nutrients beyond the super soil mixture. Wondering if anyone has any tips or suggestions, thanks!

A handful of these leaves look a little twisted. Meanwhile, the yellowing leaves are more prominent in the middle of the plant, just below the canopy

Burnt, should I throw it and start from zero?I have 1 burn auto for excessive light, should I throw this one and start from seed again or maybe flipping to 12/12? The light is farther now but maybe I can do something else than put away my lights.. my current schedule is 18/6 and the plant is around 45-50 days old
