Deja seriously you are an exception from what I can see. I am just completely baffled by your issues and am completely lost as to why your plants are showing everything from nuteburn (and you are right....it sure looks like nuteburn) to every single deficiency ever noted in an mj plant......and few that look pretty good along the way. I just don't get it. You're not in some sort of hydrohut thing are you?

I'm going to be going to my hydro store in the next few days and i will ask my hydro guy in depth and see what (if anything) I can come up with.
