using koolbloom dry

What would you think is the best way to use it. Im using mostly advance nutes but using koolbloom over overdrive due to price and just as good as i think.. ive been uaing it at the start of week 6 at half tsp per gallon with half nutes an try to keep the ppms no higher then 1400-1500 max.

I been using it for awhile now @ 1/4 teaspoon,& I aint sure I like it.It sure swells 'em up
good.When I first started using it (DWC) I was told to run it last 3 wks,I used it 3 & then
quit,still had 2 wks to go(I missed)the swelling went down,took longer to dry.I'm just not
sure. Now I do hempy and use just a little bit for 1 wk as per directions.
What do you think about it?
