Thanks for your reply :)
Yes, I bottom-water actually when the pot gets quite light, and I actually rely on the lower leaves (wait till they're bendy). It's /directly/ under my grow lights and each new set of leaves comes out like this. When they're teeny tiny, they look as though they may have the veination. Then they mature and it's pale and sickly. I'll try to water more frequently, though, I've been holding back since when I first heard of them, I got the notion that they'd fall apart at the sight of water much like lithops haha
