Hey man I've been looking through your journal and my eyes keep going back to your one plant. The Canarado plant shows signs of hemp russet mite damage to some of the leaves. However, this same damage can be caused by the light intensity being too high for the plant. I have 4 photos here for you to look at. The first one is of your Canarado plant. Note the curled up leaf edges which is referred to as canoeing. The next three pictures are of leaves with hemp russet mite damage.

Hemp russet mites are microscopic so you'll need a lighted microscope to see them. They will be on the bottoms of the leaves. Hopefully it's light damage and not the dreaded hrm's.
