I only have 45w lights on it though, I’m worried...

Hi @Hutch80! In my opinion this would have benefit to your yield, but it's too late. I do not recommend to prune/lollipop after the 2nd week into the flowering stage. Doing it during late flowering increases the risk to harm/stress the plant and loose in weight. In this situation I would try to increase light penetration on the lowest colas, by bending the main stem slightly. Next time consider buying a real led growlight such! Let me know in the comments section if you need any further information, and happy growing! 👊

Your plant looks healthy and it doesn't look too large. While your light wattage definitely hurt your yields, it looks like you trained well and kept her small enough so your buds won't be airy and have some nice density. I would only remove the bud sites at the bottom, at this stage of flowering, if you have little to no light penetrating to them. Also, if your plant reacted well to your other training techniques, then you could assume removing the bud sites wouldn't hurt her too much... basically did she handle stress well? If you could add some light to the sides or bottom then absolutely do it. good luck!! 👊
