Not enough molasses for how long your brewing...if you had a microscope you could see, check out your local library, mine rents them out! In my runs, anything less than four tablespoons of molasses, once you cross the 20 hour mark id start to see the recently bloomed microbe population start to decrease, once i hit 30 hours more than half will have died off.
I would be using a tablespoon per gallon if you intend to brew past the 30 hour mark.
From a fertilizer tea standpoint tho you're killing it! The alfalfa and the comfrey with some compost and castings will probably cover everything your girls need. It's hard to imagine things goes bad for you even if you are giving your plants half dead microbe teas.
