bushmaster?

i am running five girls on an ebb flowmaster . they have pretty much grown to the ceiling. my guy at the hydro shop said bushmaster will stop the problem bottle says to flush the res after three days. guy at the shop says it don't matter. anybody have the answer?

stop what problem..... i didn't see you mention any problem.

Personally i would never use this i have herd some Horrid thing about it ecpecially in the flower stage... from bud rot to stopping production of buds totally!!!!!!!!!!! so in other words TIE YOU PLANT DOWN!!!!! if you do use YES FLUSH IT!!!!!!!!!!!!!! get those dirty chems out of the plant!!!!!! It will do more damage then good in the later stages of plants life!!
