I am about 4 weeks into flower. I am running 9 plants in a RDWC setup. I am using CO2 @ 1400 ppm. Temperature is 82-84. I am running an air cooled 1000w hps. I am using the lucas formula. Initially my EC was 2200. This is ambient water EC of 300 or so and 1900 Lucas formula. I then phed, added epsom salt. I set the ph at 5.8 and it drifted to 5.6 over 7 days and the EC is 2900. I added 10 gallons of water to my res so the PH is about 5.9 and the EC should be a lot lower(I haven't rechecked it yet.) I just want to verify that is only nute burn and not a lockout or something I should be concerned with.
Also, bleaching under a 1000w @ 12-18" isn't a big deal is it? The bleaching doesn't hurt anything per se does it?
