I have a lotus in a large black vinyl pot, roughly the size of a wine barrel. It's located in full sun on a brick patio. It's presently forming the surface pads with a few starting to rise above the water. Most are a nice shade of green but a few smaller surface pads have crisped up. I'm wondering if the pot is getting too much heat and if I should move it to a more protected area where it would get a little less sun heating up the black vinyl sides.
