can someone tell me what is going on here?
this is my second hydro, 1st dwc

my stats are
TGA agent orange from seed
1300 ppm
4 gal o water in each bucket, transplaneted into these DWC buckets 1 week ago, so new roots are now plentyfull and touching water.
35watt air pump with Medium cylinder air stones 1 in each bucket.
ph 6
air temps are 80ish
600w HPS is on 24/7. (they were started under blue T5, but thought i would be flowering these next week, so i threw them under the 600 hps to get them going.

nutrients:
Pure blend pro, hygrozime (10ml per bucket), few drops of superthrive OG, aqua shield as directed, and cal mag as directed, inoculated with roots organizim

the only thing i can see being a problems is cold water. they are in a garage with 50F air temps. i dont have a water thermometer, but i just started putting in aquarium heaters, i have 2 and have been rotating them every 12 hours to keep the water warmer, but i just started this yesterday.

is it cold water nutrient lock out?
i am starting to see yellow leaves at the bottom (N def) today.
thanks

I agree, I keep my water on a shelf near my lights to get it as close to room temp as possible. Aim for a 75 room temp, they are quite resilient, just watch out for overwatering, over fertilizing, and maybe try stacking the buckets on top of something to get it off ground floor
