sounds very much like over feeding try diluting but before you do anything take a PH reading and adjust accordingly hope this is some help..

PH is too low, nuits locked out

I know using hydro setup ideal PH is 5.5-6.5, with your PH at 5.5 the nutrients could be absorbing too slowly? I've heard of some situations similar and bumping the PH a couple of points helped. Anyways just a thought, may be the situation maybe not.
