iam unsure but youd only want to start off with a light dose id say no more than a teaspoon per gallon.Usally when i use plant foods i use something that will have a higher n rating compared to the p an k when in veg stage an then some with higher p an k when in flower but give your stuff ago mate just start off lightly
