How do they look?

those are definitely more than 16 days into flower -- when you see signs of flower phase it actually started 7-10 days before that with an auto. still takes similar length of time to develop. they look fine. i'm going to assume the leaves are a consistent green vs the optical illusion that sometimes happens with intense grow lights. the undulations and shadows can make it look blotchy or interveinal chlorosis when it is perferctly fine. it seemss slow but it is definitely progressing. try not to think about it,like not watching a pot of water boil. it goes at it's own pace and you don't control that... just keep her happy.

They look great for 16 days into flowering! Look at the page from this strain on this website to compare with the other growers: growdiaries.com/seedbank/sweet-seeds/sweet-cheese-auto Enjoy your grow buddy!

Bud are looking on point for day 16. But your Plant looks weak , Its not as green as it should be. looks like its fading slowly, Plants still grow during the first 2- 3 weeks before it starts focusing all its energy on the buds. you should be feeding them nitrogen with the bloom during the first 4 weeks of flowering.

We're used to seeing incredible changes in plants when they're in the veg state - when they get into flowering, it always seems that they somehow slow down (they don't) because, proportionally, it's difficult to see the changes day by day. Your plants look extraordinary for this age - job well done! Now just keep on doing what you've been doing (minus the heat mat!) and you'll have a wonderful harvest. Good job!

It looks good to me. After the stretching is complete and the buds are formed, the plant is now spending her energy on ripening the buds. Just like all the other processes during the growing stages, it starts slowly and accelerates over time. For my plants, this transition takes like a week or a bit more, and that week it looks like it's not happening much.
