what is wrong with this

This is off of a jock horror autoflower under a 400watt hps in fox farm soil with the fox farm nute line up. I think its a cal def but Im not sure. Can someone give me some advice. Idont think its nute burn. Please help.

Its been slowly moving up the plant. Its 3.5 feet tall in a 3 gal.pot

its not nute burn, its defiantly a micro nute deficiency (cal/iron/mag). give them a good dose then give it a few days and you will see improvement. here are some before and after pics, just happen last week. hoped that helped

thanks thats what I thought.
