Grow big and big bloom are not intended for hydro. They mainly lack calcium and magnesium. No wonder your seeing improvement with the cal mag. Switch ferts to gh 3 part, floranova, pbp for hydro + cal mag plus, etc... By the way, their foxfarm hydro formulations are lacking...

oh yea... top leaf deficiency probably means root damage.

You think everything is root problems, is that your problem du jour?

What exactly are your grow qualifications, oh dope growing chick?
