Both these plants seem to be wanting lots of Mg. Clear lines between the veins on both plants.
Plant 1 is filling out well. Going to have one fat main cola. The smell is starting to ramp up a bit. A sort of skunky damp citrus smell. The buds look like they're going to be pretty solid too.
Plant 2 has struggled slightly all along. Not quite as dense. It's leaves have never looked quite as healthy, but it's still going on at the same pace as the other. Slight bit of leaf bleaching on top.
