Yeah I'm running ammended coco now, I used GO CaMa+ at least 1 tsp every time I watered and was fine (except the last couple weeks). it's derived from molasses i think(basically watered down molasses), molasses has cal and mag in it. Haven't watered with just CaMag+ in awhile though, i've just been dumping it in my AACT's along with some molasses, sucanat, and vermicompost but like i said when i was on a feed, feed, water, schedule ect. i always had to use cama+; on my water days I go with the "full stregnth" dose on the bottle which is 2 tsp @ 1 gallon of water. Even with seedlings because the calcium binds to the coco making it unavailable to the plant, if I didn't do this I would start to get rust spots on my lower leafs just a heads up bro be prepared to be buying that cama+ by the gallon jug instead of the quart if you're running coco! Your plants are look amazing though!
