1) Nutes way to strong at this point
2) I have never let my water sit out, I run it right from the tap but thats just me. When water sits out like that it not only declorinates but also distills, no O2. I'm not giving water that has 0 O2 to my girls but again thats me.
3) PH is borderline low. At 5.6/5.5 things start not being taken in by plants. 5.8 - 6.0
4) Light to high. try more like 12 inches, drop light then put hand just over top of plant and leave it there a sec or 2 ........... does your hand hurt? If so raise the light a lil if not leave it be
5) Rez temp is borderline high. 80 and above you start playing with chances of root rot and worse.
6) Cab temp to high!! No more than 85 unless you are Rusty in the desert
7) light cycle is good till flower
8) You can pick up a pest strip and stick it in there to help with critters
9) Calmag is a good addition. can use 5ml per gal as a preventative. Most people use the actual "CalMag" which I think is made by Advance but I am using GH's version
