We ran straight Lucas for over a year. It works but Latewoods modified is better. There's a sticky for it.

5th week of flower and your mix would be

0ml's per gallon (grow)
8ml's per gallon (micro)
16ml's per gallon (bloom)

I would read the label for koolbloom and the hydroplex it maybe too late in flower to use or it maybe like gavity and need to go in now on week 5.
