@capone304 how much are you feeding ?
PPM's ?
I don't think it is your lights, mine are 35 days into 12/12 and some of the tops are 8" away from a 640W LED @ 100% and no issues.
Which version of ProMix ?
I use ProMix HP, feed with Mega Crop one part, well water ~500 ppm, ~7.5ph. No ph down, no Cal/Mag. Currently @ 5g/gallon.
I usually don't measure ppm's but go roughly by their feed schedule and how the girls are responding.
When I did measure with Mega Crop one part or GH Maxi series 800 - 900 is as high as I could go....
Cheers
