Sure-

You want to follow the ratios on the bottle, but I'd cut the dosage per gallon back at least until I got a feel for how the plants responded as the soil dries out between waterings. The evaporative concentration of salts in the media between feed cycles isn't as high in hydro as it can be in soil- you rarely let a hydro media dry out as much as you do soil.

GH Flora at full strength might be a little hot as the soil dries out- see how it goes.

I'd also water till pretty good run-off every once in a while, to flush out any mineral salt deposits that may have built up.

I don't know if anybody has FAQd it, but there's a really popular dosing variation of the GH specifically for our favorite plant called the " Lucas Formula" - google would probabley get you there. Called for using much lower doses of the green, I don't remember what else.
