The Phal abuse ends here.

[King_of_orchid_growing:)]

It is getting a little too much light. Not enough to get sunburned. That is where the yellowing tips come from. It is easily remedied.

Otherwise, that is very close to the ideal shade of green. For the most part it is getting an adequate amount of light, just take it back a tiny bit.

On the flip side, if the green is very dark or olive colored, it is most likely not getting enough light.

The light colored edging on the top side of the leaves may be a sign of leaf variegation (in the case of Phals, it is a recessive trait). Nothing to worry about.

The underside shows signs of anthocyanin pigmentation around the edges. Nothing to worry about.

I see no signs bacterial, fungal, or viral infection.

I see no signs of sunburn.
