Seen a couple of leaves yellow but seems it’s because there's new growth elsewhere, roots or new fan/leaf, so I think nutrients are just being recycled elsewhere. They definitely grow much slower than Phals.
Plain tap water daily since April. No fertilizer.

What is your reason not to fertilize?
I don’t think they are heavy feeders but I think they certainly will benefit from it. They need their “vitamins” to grow, just like we do.
IMHO, in the end you’ll notice deficiencies.
