you use the booster the last 2 weeks of nutrients (no other boosters, like big bud or pk 13/14 ...etc should be used with that product), then you flush.
latewood Reviewed by latewood on . Need help with additives and flushing Hey I have a question. I am using a additive kinda like a booster that the instruction says use last 2 week of harvest. I would like to use flushing also which is they say use last 5 days of harvest. So do i use the booster the last 2 week right before flush or can i use the boost for last 2 week and on the last 5 day of the two week i flush with the booster. Rating: 5
