Hey Weedhound,
As a mattera fact i did I can't make a definate diagnosis. It could be mg, or N, but I've been feeding them almost full doses? I'm wondering if maybe my ph is to high. I'm using fill the vial and add drops and compare color method, and runoff is green in color after the drops are added and green = ph 7, but maybe its 7.1 or 7.2 or maybe 6.8.
What nutrients would get locked out with a ph of 7 or a tisch above 7?
