Vegging: I'd recommend not feeding it nutes at all and to get some good soil. If you want to feed it I would wait at least until 3-4 weeks into it or if there's a problem with your plants. The only nutes I use in vegging now is some H2O2 (besides mixing a little fert in).
Flowering: would also recommend fox farm tiger bloom and big bloom. i'd say a lot of people use them. Never burned it and theyre looking good.
i wouldnt recommend miracle grow nutes.. theyre harsh and it seems to be easier to burn your plants with. they work for some people, fine, but i wouldnt use them
