I found some nutrients at my local hydro store called Envy. Did a search on here and didn't find any info about them so figured I would share. I started out using Ionic and then moved up to Botanicare Tri-Flex. WIth the Tri-Flex I was having bad pH flux and had to adjust ever day some times 2-3 times a day. I use tap water that starts off at about 7.0pH. I go down to my local hydro store and start looking around. I talk to the owner and tell him I am just not happy with Tri-Flex and what would he suggest. He shows me this stuff called Envy and says he has been using it over 20 years. It comes in a 2 part mix. Part A and Part B. U mix equal amounts of part A and B during the entire life cycle of the plants. However do not mix them together without being mixed with water. Dunno why its just a warning. Also they dont use salts. Envy doesn't stain ur water like alot of nutes do. My water stays crystal clear now. Envy also has little to no odor. Since switching to these nutes I have noticed much faster growth and healthier plants. My pH stays at 5.7-5.8 98% of the time. What makes it even better is it was only $30 each gallon so $60 total.
