What nutrients should I use?

Its my first time growing and Ive been growing indoors for the last few weeks and am using the DNF A and B early growth formula. Theyre going to start flowering in about 2 weeks and i need to know what nutrients to use if i cant get a hold of DNF bloom. Or can I continue using the vegetive fertilizer throughout flowering without harming the plants?

It's kind of hard to say because everybody is going to swear by their nutrients but really you can use any. I would just look for something highly recommended and high in P and k. Experiment with different Nutes on each grow and see which is best for you. Personally, I use Big Bud and Bud Blood for flowering - it works for me but I will try out some different Nutes on my next grow to see if there is any difference.
