I use Schultz Iron Green (golf course fertilizer hahahaha) as a foliar spray for N/Fe problems. Iron and Nitrogen work together. Just go real easy, and don't use any of these products in flower except in emergencies, and then, go even lighter!
I like fish emulsion as a N fert that does not have much other junk in it.
