DWC with spray nozzles on buckets 400 watt MH pH 6.1 CNS 17 at 750 ppm resevoir temperature 68 room temperature humidity 45 to 60 percent god bud from BC flushed with clearex one week ago had this problem for a couple weeks, getting worse. Water source is 70 percent distilled mixed with well water end up with 125 ppm. Plants been in system for 4 weeks, tried everything. I think too much nitrogen. What usually causes this and what do I do to fix it? Any help would be greatly appreciated. Was using CalMag but didn't this time because I thought I had a magnesium problem. Change nutes at least once a week.
