Hi there.
I do use Pro Bloom, but none of the other stuff you mentioned. I also use calmag, (I use ro water), and hydroplex.
My last feeding I used 4ml/gallon for the first time of pro bloom, with 3ml of cal mag and 2ml of hydroplex. (Started with 2ml/gallon of pro bloom been working up and won't stop till I see burn!)

I don't have any burn or problems yet.
I have no idea if that helps you at all, it may be irrelevant due to genetics, or some other factors. Your dosages may be fine for all I know, in my log I actually ask for input on the dosage amount, because well I don't know.
But you asked if anyone else used it, I do, that's how, it works, hope that helps.

You may have some other stuff going on though, I would stick around and see what other feedback you get, I am pretty much a rookie with growing, and know just enough to be a little dangerous.
I know regardless, you will need to know the soil runoff ph, it will need to be right, did you say you were using coco, w/ miracle grow?
I know daihaishi uses coco and goes with a lower ph than 6.5?
Good luck.
