I have crypt wendtii red a pair of 20g long tanks; one with a dual t5 NO and the other a Finnex FugeRay. Honestly, the ones in the t5 NO tank look much better. Compact size and shape, nicer coloration. Aside from the occasional root pellet, no ferts in that tank.
The crypt wendtii red in the tank with the FugeRay have larger leaves, some of which reach the surface. They also have less red and are prone to algae growth on older leaves. This tank has pressurized CO2, PPS-Pro, Glutaraldehyde, and root pellets.
Now this is only one species of crypt and some do much better in higher light (e.g. - C. parva). But this is just my experience with this particular species. I suspect it is the juggling act that comes with higher and more effective light.
I would do as suggested by others and trim off melted leaves before algae gets a chance to settle on them and keep an eye on it. I am having issues with nutrient balance on another plant (AR mini at the moment) so it is still a learning process.
