Didn’t use as much in all honesty for this grow. Epsom salt, bud explosion and Cal/mag were the main stars of the grow

I didn't know it came in liquid? Their line CalMagPro, Mega Crop(all in one), Sweet Candy, Kelp. Bud Explosion all come powder form. I want to rate it high but I've never had more than 2/3rds dissolve used RO water, boiling RO water , PH 5.8 RO water, shaking, stirring, aeration, even after 24hrs same with mega crop i just swish as I add to reservoir and leave the chunks almost certain its the calcium in megacrop not mixing well. I am a noob I mix in mason jar 1tsp then add CaLMAgPro stir/shake/let rest/shake, the add to 5 gallon PH 5.80 (bumper crop down)RO water. Its the first thing I add. Sorry for the bad review I still like the product but it could be better. -Astral
