I just went and got some of the same stuff yesterday. A friend turned me on to it. he said it will help stimulate resin production. The bottle says you can use it all the way up to the end, not to wait until the end.
"If you are close to the end of your flowering cycle it would be best to feed PURPLE MAXX with plain water. Use 1/2 to 1 teaspoon of MAXX per gallon of water right up to the end"
The gentleman at my local hydro store says it is to be used as a foliar spray. Spray plants just before lights go out to allow plants to uptake nutrient in thier dark cycle, and to prevent from burning leaves. I use a 32 oz. (quart) sprayer, so I just used a 1/4 tea spoon for my 32 oz sprayer. Hope this helps.

You say you have gravity as well use them together keep it under 800ppm
