Adopting Eleven Roses week 1 flower

OK so this week I was away so this is the end of week 7 instead of the beginning of the week. As I was away, I had a drip feeding system in with just water and organic home made compost. They have put a lot of weight on, especially the one in the left. The one on the right isn't putting on crystals on all of its branches for some reason. I noticed it was considerably more damp than the one on the left and there was some white fuzz on the soil and on the main stem. I will put in an extra fan for better circulation at the bottom of the plants and begin giving them only water until they are ready.
