Cal-Mag mix/ratio

Try spray cal mag to leaves once. Calcium is immobile. Difficult to move up plant system. Spraying it is like a direct injection to the site with deficiencies.

i put 1ml/L in my grow and plant have calmag def on 10weeks from seeds in coco. put more

Whether you want nitrogen in your calmag or not depends on all the nutes you use. If for some reason your base nutes arent providing enough N then using a higher N calmag would be a good idea. Now come flower time when you back off the N it may become too much and you have to use a low N calmag. I use megacrop which is an all in one nute that works really well. I was using a high N calmag with it and had no issues in veg but once flowering hit full force i was getting an N toxicity. So i switched to a much lower N calmag. I believe my original one as like 10-0-0 or something and i went down to 1-0-0. Now this last grow ive been using only the 1-0-0 and things have been great. Still enough N through veg and not too much in flower. I usually use 0.3EC of my calmag because i run coco which loves to suck the calmag outta my water. All in all 1-0-0 and 2-0-0 are so simillar you probably wont notice a difference between the 2 so id say in your care its just personal preference or whichever one is cheaper if the cal/mag part is the same concentration.

Hey I use the Cal / Mag from canna :-) I always do it this way. I take osmosis water and mix it with normal water (the normal water has to stand for 24 hours for chlorine to escape). mix up to 0.2 ec then I increase the ec to 0.4 with Cal / Mag :-) This is my starting water 👍🌱
