I've started using a cheap dehumidifier to reduce moisture in the tent, especially during the night phase. Let's hope that's enough to keep mold at bay. Seems like the Runtz has reached its final height at 72cm. Not sure about the GSC, its height is 60cm. Defoliation is down to a minimum. I don't know how much the calmag helped, but I'm still using it. The Runtz still seems to have some kind of malnutrition or light burn.
The new small pot is basil. It has nothing to do with the grow, just using the light for some tasty kitchen herbs 😅
