Looks like you’ve done well getting this close to harvest. I think you can do even better.
I suggest you follow the below link, fill out the “support ticket”, post it back here and hopefully some of the expert growers here can help you improve your result. Without knowing more about your grow, it’s hard to offer good suggestions,. For instance, I suspect you don’t have a fan blowing on your plant … but I could be wrong. The spindly stems and need to tie it off to supports both suggest no fan. But there could be other reasons.
