Burn leaves? Yellow leaves? BIg problem? (AUTOFLOWERS)

Yellow leaves
Hi guys, unfortunately because of an emergency I had to leave my 2 babys with some friends for three weeks. At the bottom some yellow leaves and like burning signs. I don't think it's because of over nutrition. They didn't get any for three weeks. Might be not enough nutrient?

BT21 Probleme?
Hello dear growers, I'm at BT 21. Can someone tell me why the leaves of the flower clusters are turning so "neon green"? Is it due to nutrients or too much light? The lamp is quite close since there's no air left above. It would be great if someone had a tip for me!

Light or nutrient burn?
Ive been having yellow tips on the tops of both my plants for some time now, I already raised the light up a bit higher than the maximum height the manufacturer recommends, but Im still having the yellow tops. Could this be nutrient instead of light burn?
