Strip Her Down?

Check the plants for male pods on your pictures some look like the pods happy growing

Defoliation is recommended to go earlier for autoflowers. If I were you I would remove a couple of leaves every 2/3 days to make sure not to induce high stress at this stage. Prioritize to remove from the bottom 30% of your plant and do some research on lollipoping (not to be done to that level at this stage but you can learn what and how to remove from it) Happy Growing, your lady is looking beautiful 😍

inverse square law means you should heavily favor the upper portions of canopy... for every doubling of any standard incremental distance from light you are 1/4th of previous intensity. worry more about too much local humidity and fungal growth for sure, but those bud sites 2 feet lower in canopy will never by substantial buds. side lighting or internal canopy lighting would change that, but removing a few leaves above won't do much. light needs to hit local leaves.. not local buds. ppl think light on buds triggers it, but it's the energy provided locally that is more easily used that does it... cell differentiation.. maximize what various parts of anatomy are made for and not what ppl feel is happening when it seems to contradict physiology. technically any green surface likely has chlorophyl and can process light through photosynthesis, but it's extremely attenuated or significantly less dense (chlorophyl presence) than in the leaves.. meaning it is incredibly less efficient at doing so.

Looks super healthy and happy. I would leave it for now and reassess in 4-7 days.

I just noticed from day 43 to day 50 you only gained an inch. This is good. Should signify that your stretch is done for the most part

I personally lollypop mine but not as hard I guess you would say. Get a good even canopy but enough defol for light to hit the money spots. Leave like the top 3 nodes of fan leaves on each cola is a good start. Hope this helps
