magnesium maybe? i think that leaves turn yellow from the inside out and curl upwards when there is a magnesium disorder. are your grow tips a lime green?

The answer lies in your runoff ppm- it is RISING dramatically- you need a good flush, then start feeding wiht a weak solution of your fertilizer, and give a foliar feed with a weak solution of your GH Micro for the visible deficiency. That does NOT look like a straight Mg def, so no more epsom salts- you could be adding to the problem- it would not surprise me if that is what is causing your runoff ppm to be so high.
You are aware that the GH 3-part is rally meant for hydroponic applications? I have never tried running it in soil, but suspect that you would have to flush somewhat regularly to keep on track.

Thank you stinky,I flush her today misted her with thrive alive green.I dont mix the nutr to what they say on the bottle,1/4 of that.I'am using GH3part cause I will be starting my ebb&flood cab soon.What should the run off be?Near the same as the in or just a little more or less?Thank you for your help.PEACE
