You can also try tying it down, defoliating, and HST to get the other plants better light?! Or are you considering it because it takes longer than the other 4?

Leave it as it is. Lessons learned for next time...........

you would lose 80% of your potential yield if you removed that middle plant Mate I would continue as you are if possible , remove the other plants once they are ready and let that big girl finish I reckon you will be suprised with the outcome

So yoi have 2 sep 1s. Great. When the bulk of your plants are done. Take 1 light away and just use enough to help it push through its stage. I wouldn't get rid of it.. no way. Good luck

Why? This is a massive part of your grow So, what to do. Use your lamps and when most of them are finished that one that's not done can be put under lesser light as it won't be too far behind. Let me look at your lights

Just let the GSC have only 2 or 3 shoots and harvest the GSC together with the others. This way, the others have enough space and the buds of the GSC can ripen quickly enough since there are only a few. But it's not worth it to wait 5 weeks longer for just one plant. Good luck either way!
