According to the above you're giving them nutes at 150% of the recommendation. Most people start out low, say 50% and work it up.
EvilCartman thanks for the reply but I made an error my wife told me it's the 12 gallon Res and she feed 12 1/2 tsp like the instruction reads I don't have a ppm meter but the instruction she for small plants add 1/2 TSP per gallon so 12 Gallon=12 1/2 TSP right? Even if the dose is too high would the leaves curl up like that?
