@HochhausHaze, brother, we all have coconut in the substrate, you don't use just coconut fibers as far as I can see... anyway, there's no need for cal-mag so early... learn to talk to the plants, learn to understand them and they'll tell you what they need and what they have an excess of... don't follow the pattern and think like "I'm using coconut so I need cal-mag right away" no, it's needed when the plants ask for it, not when you think… now at least it's easy, you have everything on the net, you google it, you read more opinions or even better ask an experienced grower from the forum, then you figure out what's best... you literally google "lack and excess of nutrients in cannabis plants" you find the picture that's easiest for you to find and on it you have everything the plant looks like when it lacks something or has an excess... after a while you'll remember it and you won't need a picture to see what's wrong with your plant missing or what is too much... you will learn to talk to them and everything will be much easier afterwards This is well-intentioned advice, now it's all up to you

@Radagast_, i have to use calmag as im using coco and my tapwater doesn't really have any on its own, thank you
