Ascents in Rock Star as Retreat

Got up to the sixth bolt clean, managing to take it slow and careful. Then just could not for the life of me work out what to do to get to the last bolt. Under the overhang things are clean and dry and conditions were good, after the overhang the last bit of gulley was just green with moss, maybe there are holds around but struggled to find them.

Had a few goes pulling myself up and looking for a decent hand to stabalise and clip but no joy. In the end had to give up. A bit gutted cause things had gone so smoothly till then!

I don't know if it just needs a thorough clean near the top, whether I'm missing something obvious, or whether something's come off, but just couldn't get to the 7th bolt. Will take my stick clip up next time to clean off the mallion and maybe give it a clean up there and see what I can see.
