How long into the flowering stage do I use the mix of 2-2-2 or do I skip that transition mix and just use the 1-2-3 mix

Mixes are referenced in order of Grow-Micro-Bloom
pskipper Reviewed by pskipper on . GH nutrients Is ther any special way u have to add the GH 3 part solutions to the resivior? I've heard alot that you have to mix the micro then the grow then the bloom is that true? Only reason I ask is that I went to the GH website site and it specificlly said order does not matter.
