I sprayed with some cal mag, but covered the flowers since I thought it was a calcium problem. Only two large fan leaves are being affected, the rest are fine. Thank you all for your help, I will wait and see if the Cal-Mag does the trick. Always good to have outsiders perspective!
I’m new to growing, currently week 3 of flower with northern lights auto. Can someone PLEASE shed some light on what this is and what to do? Below you will find a pic of a leaf and what my feeding schedule I follow. Any info is appreciated!
FYI 600 watt full spectrum grow light, humidity 38%...
