Yeah, on the MC website it says to use that much for extended veg, bcoz I think MC say to switch on week 4..... I would normally switch to bloom nutes at the end of wk 5 so I left it in at that........also I thought it kind of makes the jump from a veg to a bloom dose softer IMHO dude.....so I left it inNice 1 bro. This may sound stupid….. but is it week 1-5 on the veg then effectively week 6 u upped it again?
