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?

@vince.s.cannata Technically there's no such thing as CalMag deficiency. CalMag is a plant supplement comprised of calcium, magnesium, and often times nitrogen. Here's some more info on calcium and magnesium deficiency: https://www.royalqueenseeds.com/blog-calcium-deficiency-in-cannabis-plants-n602
