You want might want to try some Rootwise. They have the basic inoculate and they also have one for flower, it's called Rootwise Biophos. I alternate between that and Recharge. With the way you're using it I'd add a small dose of molasses like maybe a half to a quarter teaspoon per gallon. It'll help the microbes and it does have a lot of micronutrients. Especially good for late flower I think.
