i use botanicare pbp in all my hydro. dwc, nft, whatever. the ladies are usually happiest at about 650-700 ppm (1.3-1.4 ec) in dwc. whichever nute line you end up going with, silica is definitely a good idea. for beneficial bacteria, i recommend hydroguard in conjunction with pondzyme w/barley. these two products together have been very effective for me- in some gardens i have worked in, res temps have gotten up to 76f with minimal to no root problems. pbp additives that ive found to be useful/effective are sweet raw, hydroplex, vitamino, liquid karma, silica blast, hydroguard, and obviously calmag.
if you prefer to stick with gh, look into the lucas formula with the flora series. i havent used it myself, but i have seen others use it successfully, and its very simple. if you go this route, i suggest diluting (or adjusting dosage) to around 650 ppm. the standard lucas formula seems to run a bit too strong for my liking. also, if you are not using r/o water, remember to get the hard water micro. if you are using r/o water, get the standard micro, and you will probably need to throw in some calmag.
a friend of mine uses the two part B.C. system with dechlorinated tap water and gets good results. i havent used this either, but i have smoked the end result, and it definitely holds up.
your maxi series stuff should work just fine, too. i have heard/read of people running it successfully in hydro. but personally, ive never been a fan of dry nutes for hydroponic applications.
there are tons of options for nutes out there, most of them will do you well when you get them dialed in. the only thing i can recommend against is advanced nutrients. i dont want to get into the whole an bashing thing, but suffice to say that i have have their products to be most inefficient.
