Is 90F substrate temperature cool to the touch? I measured the temperature of my hand last night, and its 95F. The reason I'm asking is that my vet told me to take away all the UTHs; he discovered that the underside of my leos' feet became pinkish, which they really should be white; they're probably getting mild burns from the UTH.

I placed a lot of rocks on the warm end of my tanks, and have a thermometer stuck about 2 inches above these rocks, and it reads 90F; but the rocks are quite warm to the touch. I haven't measure the exact temperature of these rocks, but if they are warm to my touch then they're probably over 95F?

So, I turned off all UTH last night, the surface temp of the rocks read 90F. Because these rocks feels cool to me, I can't stop thinking that my leos aren't getting enough belly heat. Is this suppose to be right?

The ambient temperature is 86 degrees; the measurements of my tanks are 21"L x 14"W x 12"H. The temp at the hot end reads 90 and the cool end 88! Can't really say I have a gradient there. What can I do?

Not too sure on this, but since belly heat is more important than air temp, try lowering the temp a bit down. What I have is the UTH on low under a cave, inside the cave it reads 89F, but since the the walls of the cave a thick it kinda holds that hot air in there, allowing me to keep the rest of the cage cooler. I have a low wattage bulb to keep the hot end temp up at 85, since if hes cold he goes in his cave to warm up, where its 89. Having it only 85 outside of the cave helps me keep the cool end down to 80. Really just find what works for you, took me a while to get everything near perfect, and the geckos are troopers so they'll be fine while everything is getting straightened out, good luck

Well, rocks absorb the heat real well, so if you've got a UTH AND lights, it might be getting too hot. If you used substrates such as slate or rock, these like I said absorb heat real well and sometimes well enough that you dont need an UTH. I'd take the advice of your vet, if its changing the color of their skin then its probably too hot. 90F is'nt as hot as it sounds as a surface temp, and if a human hand is 37C or 95F, then 90F is gunna feel cooler than your hand aka cool to the touch.
