I think i had about 5 sets last week.. Hard to remember sometimes. They're definitely growing quick now though, because I have to raise the light a lot more than I used to. They seemed to have liked the nutes I gave them a few days ago though.. no burns, just seemed like they picked up on growth.. Will add more nutes next watering since this last watering was just water. (I don't really follow a watering schedule, I just water when it's no longer moist when I stick my finger in the soil a little bit. Generally that's 3 days, but sometimes it's 2..)
