If you use Rev's cheater as a tea and don't feed it more than once every 2 weeks it will do wonders across the board.
Feed it in lieu of a top watering when the plants are quite dry and water in as much as you would water with if it were water. I wouldn't let excess sit in the reservoir tho.
The microlife will be fine with it if it dries down between use and the next watering. Use molasses in it too.
If you are going to administer a feed you may as well boost the microbes too. Molasses does that.
So if you went EWC, guano, molasses, fish ferts, and water you would be feeding the fungus with fish, the microbes with carbon (molasses), and adding P and ewc.
That's a recipe for high brix priming if you have good soil calcium in place.
So decide if you should use dolo water one more time or not, then concoct a potion/tea that fits the above recipe and try it. The sugar is important here to boost brix, and molasses is the best, so if you want to concoct a sugar potion for future use thats cool, but for speed and reliability right now I would just use molasses for now and potion in the rest if you can.
It should work, but you may need to feed it semi regularly to keep brix up, so you may have to work it into your rotation, and thats because your soil isn't fortified enough this round, but once you get the soil stronger a tea like this could easily prime a good brix run.
