it depends on what ur feeding them atm?

i didnt start adding canna boost until week 2 when i saw lots of bud sites and saw the hairs on the buds streching out.
in 1 week i will also add pk/13/14 for 7-10 days then i will double up on my canna boost for 2 more weeks then flush for 7-9 days
leevilla Reviewed by leevilla on . nutrients before switching to 12/12 hi i was just wondering if anyone had an opinion on this. should i give my girls a low dose of flowering nutrients right before i switch to 12/12 to kind of break them in? dont want to if it wont be beneficial or if it will hurt them. any advice would be great. thank you.
