For strong healthy growth when the lights are on 24 hours a day to see how big the plants can get, use a fertilizer with a high first number. 19-19-19 is good.
For strong flowers (buds) when the lights are on 12 and off 12 hours, use a fertilizer with a high MIDDLE number. 12-17-12 something like that.
thats fine.i use 24-8-16. just go lite at first 1/4 to 1/2 strength to see how the react to that. if things look good after a few week or so then you can go up a notch..
what you have is a very good veg nute.
