Indoor Big bang auto help plz

[StChristopher]

Hi, I'm have real trouble with them.

Tent 4x4x6.5
600 MH
Sun shine adv mix#4
temp lights on 78 (lowest I can get) lights off 70 20/4 36" over plants
2x in 3 gal pots at 3 days
2x in 5 gal pots at 28 days

First problem, my 3 day old is showing tips pointing up like a claw (only one of them). Heat?? Light stress???

The 28 day olds have real problems, their only about 10" tall, I cant seem to get their feed water right. I tried Lucas formal at 50% Feed water water once a day. Leaves twisted burned. Then flushed just water for a few days now all my bottom shade leaves have yellowed and died. Tried GH drain to waste flora series 1 week at 25% leaves twisted and yellowing from stem out.

Any one could give me help with feed/water that worked for them??? I dont have ec meter do ph after nute my water at 5.8. Also growing a pure kush (photo) and have no problems with feed water on it. What am I missing here Kush doing great Big Bang cant get it right

No pics, I'm old and have no need for all that kid stuff (smart phone). Hell I still use a land line....Guess I was asking for someone that has luck growing these (Big Bang) what they water and feed them, I'm using GH 3part. Sunshine is a soilless mix peat/coir/perlite
