I Just started giving my plants big bud yesterday, and I'm not sure if I'm supposed to only use it once to increase my yield, or keep giving it to them.
I bought this product for the first time this year and been using it for 2 weeks now. I can already tell a HUGE difference. I started off using half of what the bottle said. After the first week, i started using the full amount. It says to only use week 2-4 but i think thats bs. Guy at the hydro store said he uses it all the way through and never had a prob. Mix that and molassess in with your water and watch that bitch swell. Very impressed with big bud so far. Hope that helps!
if that's a pk booster, you're supposed to use it for one week at week 5 of flower. remember to reduce your base nutes when using a pk booster, or you could burn your plants.
