GSC is more of a Kush type strain and like a lot of CalMag. You could up your CalMag 20%. Watch for dead spots on the leaves. If you get them, you need more CalMag.
Oh wow! I just started GSC XTRM from Amsterdamn Seebank and got this and was driving myself nuts trying to find what the problem is. Just the tiniest spots on the bottom leaves but otherwise the plants are healthy and thriving. Glad I read this! Thanks!
