Hey guys,
This is my first post although I have been lurking for years. These girls are 12 days into veg from clones. This is a new strain for me, ice cream from paradise. I am running them at 2.0 ec and ph at 5.7 and both are very stable, growth rate is good, but, my older fan leaves have been curling/folding up and developing 'rust spots' and newer growth is twisting, all in the past 5 days. Other than strain another new variable is I am using RO water as my well water has always been a pain to manage. They are 18" away from a cooled 430 hps so I don't think it's a heat or burning problem. According to my research my best guess is it's a magnesium deficiency, the only thing I have done so far is foliar feed with a dilute magnesium sulfate solution.
So, I was hoping that someone could please confirm that is is a magnesium problem and how to remedy it (ppm of mag sulfate in res), or if it isn't help me figure out just what the problem is. thx
