thank you for posting on my thread. however i checked the labels on the foxfarm nutes and is printed clearly specifically designed for hydroponic systems. so i'mm leaning towards a lighting issue. i'm using 2 400w hps and 1 1000w mh the three lights are in seperate dome reflectors air cooled i keep the hps around 15" off the plants higher on the mh. i went to a sheet metal shop to have a reflextor made to hold all three lights in a 4x4 reflecter the size of my pan. i am using a lower nute solution some of my leaves were starting to yellow. any other advice is greatly apprieciated.
