For liquid life grow & bloom during flowering they suggest a
range (see week 3)
If your plants are healthy use the full amount, if plants are
struggling use smaller amount
Just be sure to keep the ratio the same ie. week 3
use 2.5 grow & 5.5 bloom or 5 grow & 10.5 bloom
This is a good recipe for the "feed, feed & flush" method in
soiless mixes
