For fuck sake, keep a check on your EC when using the Overdrive mate....
The first few times I used Top Shooter, I cooked my plants, so lower your A&B right down before you add the booster....or else you go from say EC1.0 to 1.3 very quickly!!!
In my case I reduce A&B from 0.3ml/L to 0.1ml/L to keep the EC maintained at 0.9 when I add the Top Shooter. In your case the dilutions will be different, but all the same Bro, watch out.... easy does it!
I'd make up a smaller mix and check the EC before mixing up a bigger amount. Adding plain water to drop the EC is a quick fix for a small mix, but ultimately you'll be diluting everything, so the Cal Mag will drop etc, at a time you don't need it. Easy does it, yeah?
