Why so yellow and curled?

Got these about 2 weeks ago in rockwool. I transplanted them in a 70/30 coir/perlite mix and put them under a 400w mh.

I fed them twice with heavy 16 A&b, calmag and root bloom. Ph'd them @ 5.7 & ppm 500 first and 800 the second time. When I saw some burned tips I flushed em with 10ml/gl of clearex. Now its been 4 days since the flush and they're turning a little yellow.

I'm also concerned because several of them have leaves curling down. Why is that? It was over 80* for about a week but its back to high 70's again. Is that related?

Also I've been spraying them every third day with Azamaz and other days with Einstein & Wet Betty. Too much?

you totally need to back off on the nutes if i were you i would flush with just plain water and not feed for couple weeks.. the dirt has all the plant needs at this phaze.. root stimulant wont hurt..

Well they're not in soil, they're in Coco so it has nothing the plant needs at this phase. And not feeding for a few weeks?!?! Hell, I only veg them for 3 weeks tops before they go into the flowering room. If I didn't feed them for weeks they'd be half way done.

sorry i missed that about what your growing in.. but that doesnt change the fact that you are over feeding them.. do what you do man its just my oppinion..

give em a lite dose of ur nutes

OK.. OK.. thanks guys

like 1/4 strength...see how they react.!
