Oh, please. Who would say such a thing


I think I found the problem
So I did a runoff once again. ph = 7 going in, 6 out the other end...judging from the chart posted in the sticky of the plant problems forum, P, Ca, and Mg would all be locked out at this pH (less than 6). I flushed with over 3X pot size (12 gal) to a runoff of about 6.7 we'll see how things go I'll keep y'all posted!
purpleskunk777 Reviewed by purpleskunk777 on . Possible Magnesium Deficiency? My 2-3 month old clones are experiencing yellowing of new growth. The yellowing is localized on the perimeter of the leaf, leaving an arrowhead-shaped darker, healthier green in the center of the leaf. Researching google, I diagnosed this as a magnesium deficiency (whether I was right or wrong) and followed the directions posted under the sticky "epsom salts = not miracle cure)," spraying the leaves (yesterday and today). The condition seems to have become worse since applying epsom salts. My Rating: 5
