All my plants have purple stems on the leaves at this point. They look totally healthy besides that. Not sure how to resolve the issue or if it is not even big deal. Just don’t want to negatively impact yield. Any advice?
Week 4
Leaves. Color - Dark-purple

This could be a pre-sign of magnesium deficiency, but your leafs would not be in such good shape. Since all your leafs are looking healthy, and not showing any other sign of nutrient deficiency, this is probably strain related : no worries ! I'll be around, waiting for your next update, until then good luck with these beautiful girls bro !

You should probably switch out the cal mag and start using a mag sulfer product. It will help with the purplish petioles while adding something that your plants will be craving at this stage of growth

I have this too sometimes. I’ve been told that it could be a phosphorus deficiency, but upping the P nutes didn’t seem to change anything. Some also said its normal with certain phenoms. I stopped worrying about it since all else seems fine.
