The picture with L/F meaning is gone from this forum -> no exact comment on which tower to move.
If L/F are high the same amount and R is low then you probably need to:
* adjust the tower against R so that it R is hight the same as L/F
* adjust diagonal rod and delta radius so that RLF are the same as XYZC
Each partial tower position (or also diagonal rod or delta radius) adjustment to will need endstop adjustment first.
It is hard to fix it using manual calibration only. Rather try Rich's firmware or calibration.wxm notebook (if you are good at math).
