The ph of your runoff is low because its supposed to be. It'll rise as the soil dries. Not all elements are available to a plant at one time ph has to swing for this reason. Kool bloom to my knowledge isn't a stand alone fert, but a bloom booster make sure its npk is what you need at this stage of growth. Venting the exhaust out of the garage should help a couple degrees right now you're just circulating hot air. How much of a difference depends on the size of the garage it may not make a difference at all. good luck
5.6 in a soil grow? You don't think that's a little low?
