I've been having very similar problems to you right now and my last grow was exactly like you described. At what strength did you feed at? I'm really thinking we aren't feeding enough. I'm assuming you weren't feeding at full strength.
From 1 to 2ml of each, what means half strenght.
I do not believe that stronger feed helps against deficiencies, if ph is out of range. It just makes things worse.
PH perfect works good only with proper water and seems that my tap water is too carbonated. Even with small proportion of tap water mix woth RO, ph goes up crazily. Seems that stuff in our tap water disables ph perfect agent in nutrients or makes some unwanted chemical reaction.
Some say that AN snake oils might help, but I remember coco grows on net, which brought 180g per plant with only basic AN Sensi line. And we have seen so many succesfull grows with half strenght of nutrients, so that the idea of stronger feeding does not seem to be a good solution.
What kind of water do you use?
