Fastbuds Grow Dec 2021

the 2 LSD-25s that I started 2 weeks later than the others are now the biggest plants in the tent. The 4 more mature plants on the outside corners are getting frosty and losing a lot of leaves. The 2 younger (but bigger) plants in the middle are developing nice purple colors and even though I haven't fed them anything but water they look pretty healthy to me. The have some discoloration in some of the fan leaves but that's it.
