Yes you threw me off with min ferts but 3/4 fert with high Nitrogen in flower is not good.I do not know what fert u are using but the other numbers are kinda high aswell and usualy reserved for a stresser fert for the final 2 weeks.I do not know much about stresser ferts nor use yet but like I said the NPK values are kinda high to be reg ferts.
I would ph water flush if in soil let dry out (not bone dry) and work up from 1/8 strength judging from those numbers.hopefully someone with more experience will chime in.
this is what I use for passive hydro but will work for soil.
