You’ll Get that by continuing what you are feeding them and time.
If u wanna use overdrive do one plant not all of them.
Growing weed is all about balance of nutrients. Don’t alter unless they are showing signs of hunger. Adding overdrive which I suspect is high in P and K will most likely cause issues.
Since this is your first time, I think the other guy had a good idea, which is to give it to one or two of your plants only and compare the results. It might save you a lot of money in the future, and if your plants don't like it, it might save your harvest too! A lot of people have ditched bloom boosters either because they didn't make much difference or because it changed the taste of the bud. Just be careful, that stuff is strong!
It’s just my opinion i brought the whole range few years back and followed the feeding schedule to the letter don’t think it made the slightest difference in fact made Final product a nasty smoke if anything
Just my opinion on overdrive.... I keep my reciepe very simple but I actually used overdrive for many years and loved it. I tried with and without and noticed a difference. Seemed like it would “finish” the flower off better. Don’t know how else to explain it. Haven't used it in years because I started doing large grows and simplified my recipe even more, but I did love it about 5 years+ ago. Just my 2 cents to help you make your decision try it on a plant
