Nutrients?

I'm on my third grow. I'm growing in grow mix and was using General Hydro nutrients.....but I seemed to have a constant battle with over-fertilization. I am using a store bought 18-18-18 now. I'm just wondering If I will get better results If I switch back to General Hydro...just back off on the strength.

would say keep using what you are now just dont use it for one watering and then start over at low strength then work back to your regular strength doses
