Hi i always include 0.5 - 1.0 ml/lt in all my waterings and feedings and everything is fine . im also a beginner so better get more opinions on the matter . i have the same nutes btw . i also find it convenient to be able to increase a small bit the EC with calmag to the desired levels by the numbers i wrote in the beginning of the message
Some base nutrients have enough calcium and magnesium so you don't need CalMag. I'm not sure about Sensi Grow A & B. You could always try without and then add in if you see calcium and or magnesium deficiency. Or feed a small dose every-other like you mention to safe side it.
thanks for the responses, fellas. i will hold off on calmag for the time being, until 1/2 way thru veg, then probably hit it with a little bit every other feeding. i know yellowing of the veins is a calmag deficiency, any other signs?
