30days old autoflowering , Problem?

[BigBangTheoryy]

Hello my autos are 30days old from seed, they are in soil/peat/perlit mix, i use hesi bloom on them and last 2 weeks i was using NPK 6-1-2 but now im done with N feeding and going for pure hesi bloom.

they are under 12/12 and 400w hps dualspect.

Edge of top leaves are turning yellow what dose that means? all leaf is green and good but edge yellow... is this overheating or overfeeding? or underfeeding?

Pardon me for panic msg but i really dont want this crop to die its medicine for my epileptic wife and i dont want big problems later on..

and im saving on energy bill


As of my question can you tell me whats wrong with leaves?

If you go 12x12 with a autoflower you will lose most of your weight.. I use 18x6 the 6 dark hours is for the hottest part of the day.. 12pm to 6pm

do you see the how your leaves are twisting like a pigs tail? that means there hungry and you need to up your basic feed..

unless its to hot in your room .. they look hungry..
