I think I've seen those before but thank you. Truth is, I've been looking for a reason to get rid of one and make some more room for the rest. So I removed it. I really felt like the other four need the space.

Aside from the big plant, supposedly mango kush, the others have had a really slow 2 weeks. Not much has changed, gained a little height, a little new growth, but not much more.... Or less for that matter... They still look healthy and are not showing any other signs of stress. I'll get a few pics tomorrow. Thank you all for the help. Keep it coming.
