Does anybody know what these grey/black blotches are? Why happened and how to treat? Have been using cacti feed once a month ?

    Could be damage from water splashes if they are in full sunlight.  Scorched.

    I agree .Also I wouldn’t feed so often ,I’d cut back to 6 weeks rather than monthly .
