FIrst Timer Automatic, Pyramid Seeds.

Seems that one of the 3 of the plants is herming, noticed some swollen calyx low in the plant that had underdeveloped seeds in them. I wonder if it was caused by the Ph being messed up early on, or is it from the nights being too cold, or both. Noticing a couple spots appearing on the leaves of one of the plants, assuming it is too late to totally fix it. But it doesn't seem to be getting much worse. Been defoliating like 1-3 leaves a day, as to not stress the plant too hard. The plant isn't smelling super heavily, but it sure smells nice. It is like a subtle berry/flowery smell.
