Anyone know what causes this?? Every single grow no matter what strain
I thought maybe it was magnesium deficiency so have been adding some canna mono 1ml/L since the start of this grow but doesn’t seem to make any difference

These leaves will eventually die but I’m only 6 weeks into flower

I think it could be Light Burn - I do have my plants fairly close to the LEDs
