First, yes talk to the CFI.
Second, get all the pre solo stuff out of the way - exams the school needs before solo, EFATO etc.
Then I go with
Also by the time I had about 4 hrs in the circuit I asked to go and do some GH and a bit of basic Nav when I went back to the circuit I managed 3 unaided circuits and to my surprise the FI jumped out and let me solo
. I had a student I had inherited with over 60 hours, had flown with other instructors including the deputy CFI and all these had recommended he pack in took him out of the circuit and did some GH with just a few circuits at the end of each trip and he got solo OK.
Good luck
