I never used root tabs with them. Just excel and they grow like crazy. Sadly I'm having issues now so they don't look as good but hoping to have it all cleared up soon
I would reccomend some sort of root tabs swords and crypts are extremely heavy root feeders and don't benifit much if any from dosing the water column. That's probablly why yours aren't doing to well. I would reccomend Ru-tabs from peabodys paradise or osmocote plus tabs from people on here or the planted tank. They would benifit greatly from them.
