I didn't skip a week! Just realized my start date was wrong and the girls are a week older than I thought. Also, apologizes for the lack of photos. Taken more, but they really show no real progress.
Early in the week, switched to coco instead of DWC. Was having problems regulating the pH (faulty pH tester -- new one on way) and didn't want to risk failing another grow. So far, the girls don't seem to mind the change. After the transplant, I've been noticing a steady increase in size with both strains, so hopefully for week three we'll see them really take off.
