Well as I see this forum gets like 20 views a day still I figure this topic is a popular one so I will add a bit more enlightenment into the subject. I have now had more experience with the purple maxx and have been doing some experimentation. I feel its best if your using ro water at a ppm of 15 or lower that you should never exceed a ppm of 325 (using fox farm products atleast) I add purple maxx at 1/2ml a gallon first day into flowering, second week I dont apply the third week I apply at 1 ml a gallon. and fourth week and 2 ml a gallon. YOU MUST get your plants used to this product for whatever reason or you will get severe burn but not if you use slowly. Now when you add the purple maxx you may notice your ppm does not change at all thats okay it will almost double in 24 hours, so dont go adding more. There was no odd taste of any sort with the purple maxx on the bud or any retardation of trichomes. It did aid in the purpling of a few plants. You have a 30 percent chance of it changing the color, however it does add to the trichome production very nicely. I do however move my lights up 4-5 inches for around 15 hours after watering with this. (I have a 600 watt hps air cooled with a 466 cfm ecoplus inline fan). I dont know if I left anything out just ask
The snow storm-adds to the stacking of flowers most definently its ridiculous however I dont have alot of experience I like the fact that purple maxx is 100 percent organic snowstorm is not because they do concentrate it more themselves but the ingredients themselves are organic except one small chemical dont know what it is. but I will use it occasionally with the purple maxx using the same dose purple maxx and adding 1-2 ml snow storm with it.
Gravity-Most definently hardens the buds, after drying all my plants that have this product applied are rock hard, however do not overdo be very light it will burn your plants horribly, and move the lights up atleast a foot after application for a minimum of 24 hours. I use 1 ml a gallon the first application the second at 2 ml and the third 1 ml, as the bottle sais you can use up to harvest, and I never had a strange taste or any type of a problem. It really is a great product if you dont mind some form of chemical fertilizer, I had a 56 percent increase with the product which is quite amazing..
any questions ask
