Plants 1, 2, and 4 look really nice, but the flowers on plant #3 don't look as nice as the other plants. It's been extremely humid here all summer, so I've been having a hard time keeping the RH down even with the AC running full time in the room, and I think plant #3 is just not liking the higher RH. Each plant received 0.6L recharge.
@Inganjawetrust, Thanks! I harvested them the other night and found one more cola with mold. I still got a nice yield, though, so I'm happy about that. It was just way too humid this summer here.
