Should i cut them off?

Check the trichomes yourself first to make that decision. Not just the buds up top, but the mid section of the plant too. Not beneficial to sell yourself short after all this time.

Now will give you a more brain bending THC influenced head high, waiting another 7-10 days will give you a more CBD influenced heavier/sleepier body type of stone. Let your desired type of effect guide your harvest timing! Personally, once they have 97-99% brown pistils they will be in the "10-30% amber trichome zone" without having to look too closely and therefore, certainly in the harvest window for peak THC levels and is my preferred harvest timing. (just a very few white pistils left, right at the top of the buds) Once they have 100% brown pistils, they will have the heavier CBD type of stone rather than the THC high associated with buds picked slightly earlier.

That is a personal preference on ripeness. You are in the window to harvest. 🤜🤛🌱

Only you can decide that. From them pics it definitely looks ready to me. Have you got a scope to check the trichomes ? As long as they are milky I'd chop them both, also the importance of flushing properly.
