i have read on my cal-mag bottle that iron doesnt stay in the nutrient solution too long when a mag drive pumop is working, in my aero systems i have used 1500gph pumps and never an issue, the minute i threw clones in my larger system immediate iron deficieny, could it be from the pump? the new pump is only 200gph bigger but size wise is much larger. my water is well aerated, the cal-mag also said water to needs to be oxygenated along with a grounding rod. i added cal-mag and i see green trying to come back, but its not feasable to add cal mag every 3-4 days, it also can be from the PH flux, i set my solution at 5.5, within 24 hours its at 6.5, and i know iron is locked out at 6.0 and up, i currently use GH 3part with the hygrozyme and cal-mag supplement, i chucked the rez and am currently going with botanicare. what are your thoughts guys? could it be the pump? the PH flux?as we speak i have the clones in my small unit drinking up some dyna-gro, this stuff is very PH stable and any plant i fed this to loves it
