But I will say o have noticed that if ur using it every watering like I have would do a regular not overloaded but decent flush at day sat 35-40 then come back with a little higher amount of mega and bud explosion then repeat it again say 20 -30 day later maybe depending on strains run Time, imo a flush that just cleans some Build up out and drys out in 2-3 days tops, I say this from the sour I just ran and just its two little flushes I made I could see a nice burst after I came back with the mega after I did this which makes me believe I could do the same using the mega and bud explosion, but I will be uping the amounts after each flush, if this makes sense I really think someone that's dialed in with thier set up and nailing an autos phases will nail perfection each time. Thinking each flush to have say 2-3ml/gal hydroguard and cal/mag pro. I know someone has some input here??? Maybe it will help speed up the growth.
