So I picked up some of the good ole purple maxx gravity and snowstorm ultra and I am just wondering...Does the purple maxx really increase the intake alot. and is it alright to use all three of these at the same time? I used some purple maxx already about 2 ml per gallon and I am in a soil grow. as well as 3 ml of snowstorm together. The purple maxx actually did make some growth begin to purple within a day but my plants showing a nitrogen deficency and it sais not to use nutrients with it...
