as far as the 3 part grow micro and bloom, add the same amount equal parts as it recommends, but use about 3/4 strength or if you went down to 1/2 strength then use that. but add equal parts like the ins ructions say. next time when starting the nutes as they are babies, use less than you started out with, when the tips of the leaves curl up and yellow like that that is nute burn, back off the nute dosage. Advanced lowered their nute dosages about 3 years ago and people still agree they have to lower even more. they are very potent, lol, you would think they would market this and say they last longer or dosages are smaller, but they just let us burn lol, it happens. general rule of thumb is to start out at half nutes though, unless you know the strain and it likes the heavy nutes.

some people don't flush at all only a water only regimen at the end of the grow. but even at the end a flush on the last 2 week mark is good then nothing but phed water to finish them for the last 2 weeks. but AN has over drive for this last 2 weeks as well, but those additives are insanely expensive and most don't use them. but they are good, however you can get cheaper stuff as well, with an exception on the overdrive, that is one of the only products like that. a good one on the cheaper is roots organic beneficial, usually about 12 bucks versus the 160 bucks of AN tarantula and voodoo juice and piranha. not exactly a good estimate but AN will last longer and is better but for the beginner 12 bucks is not bad.
