I purchased some Rotala Macaranda a week ago, the plants appear to still be healthy but they are loosing a fair amount of leaves. C02 a good amount of light, flourish. Any ideas why?

If they'rees, I'd say lower leaves, I'd say light.

I've also found Macrandra to grow better at slightly lower temperatures, below maybe 76F.
