Day 54 and no bud forming, bottom fan leaves starting to yellow

There is definitely bud forming. Those clusters of pistils are where the bracts/calyxes are forming. This is the way. Sometimes autos do seem to stall out like this for a week or two mid flower I’ve noticed. You can’t judge by the day from seed either. The seed companies tell you a timeline that is false 90% of the time. Autos usually take 70-100 days from seed in my experience

12 hours of light is barely enough for an autoflower, you need to increase this to 18 hours, even if you combine 12 hours outside and 6 hours indoors, growth should increase substantially. Cold temps outdoors can also slow growth dramatically.

You sure its not pollinated looks like it has lots of nannas but happy growing

Hi! So your plant's calyxes are a good size which makes me think she'll be popping a lot more bud soon, dw Probably the change form outside to inside was a shock to her. Sometimes you just need to give them a little time to adjust! Sometimes can be a week or two before they recover and start shooting again!
