It does look a little dry. It could just be end of summer blues. It is hot here to. 90-100. I find that they rest in the summer and this is just part of that resting. It does sound that you could do a once a week till it plumps up and grows. It should go into bloom.
OOH OOH OOOH, I just thought of the most obvious problem. DO you still have it in the dirt it came in. That may be the problem. If it is a peat based soil, it becomes hydrophobic when dry, and the water that you give it is just running through and none is getting to the roots. The plant reads the soil as dry.The soil get hard as a brick and won't re-absorb water without soaking the pot. A good gritty mix is good for it I think. Water flows through but wets it but is fast draining. A plain succulent /cactus soil is too rich and dries up into a brick . one can dilute your soil it with 1 part perlite to 1 part soil but I like to change it out to a gritty mix. There are many formulas for dirt. I mix chunky perlite ( not the fine stuff) , chicken grit, scoria, expanded shale, Washed Decomposed Granite (any combination of what is handy) for 70- 80% and some native soil or 30%pine bark fines and organic leaf mulch( combined) and Tsp blood meal. I wish I could get pumice. If you search Gritty mix or soil mix in the search bar below, you will get a head full of info. There are a lot of opinions.
I will remove ALL the soil from around the roots. I do it by soaking the plant and a gentle hose action and then I let the plant dry for 3 days for the roots to callus from their bruising. I then pot them up And don't water them for a week. They will live.
