Has anyone used the product overdrive for the entire flower phase? I have it and it says to use it during the last 2 weeks but I'm wondering if I can plump up my buds using it now.
You can't make a plant perform outside the boundaries of it's genetics. All you can do is make sure you give it everything it needs. Your plants look in excellent health and I think they will give you their all.
In both organic and hydro, the plant can only take what it needs, you cannot force a nutrient into it. All you can do is make sure that what it needs is there in abubndance. No deficiency at all? A booster will do nothing. In later flower deficiencies arise easily and then a booster is of great use to you. Low N flowering boosters in the last few weeks help smooth the last bumps...
And yes your buds will fatten up tremendously in the last few weeks, they get very exciting as you watch the calyxes swell and swell.
Seriously, your plants look excellent.
