Covering change and some problems

I found some leftover blackout cloth, so I’ve changed the covering. It seems to block light really well. The jars are cylindrical, so it was easy to work with. I also put number stickers on them for the names Alpha, Beta, Gamma, and Delta.

The new covers are nice, but the perilla plants are definitely having some difficulties. Delta is drying out, Gamma is yellowing and drying out, and Beta is distorted. Alpha is also yellowing a bit. What’s going on, you guys? 🤔
