co2 and foiler feedding question +rep

ok i have 2 questions!!

1.when foiler feeding in flowering do u do it daily untill u see budsites? and then do it on the fan leaves only??

2.when is the best time to use the co2 i know during flowering is the best my question is do i wait till i see buds or wen i switch to 12/12??? thanx

1. never foliar feed in flower. ever. you will get mold and/or chemicals all over your nice buds
2. you can use co2 the whole grow

dont folar feed in flowering, and use c02 whenever

thanks i heard that u can foiler feed just the fan leaves but not the buds thats why i mentioned it!!!
