i use that stuff this year and a few years previously and it works great, i use it with other nutrients because it has no N which plants still need lots of in the beginning of bloom.
once in bloom when they were nice and green from top to bottom i would use just Morbloom at 10ml per gallon (2tsp/Gallon)
if they were showing yellowing from the bottom up i would add 5-10ml per gallon of MiracleGro 18-18-21 and the Morbloom
i normally give my plants just water first to get them slightly damp, then use this mix at about 1gal of nutrients for every 2gal of dirt.
my cycle changes depending on what the plants need, but most of the time its water-fert-water-fert.....etc
hope this helps, and check out my journal to see some plants grown using Morbloom.
