Leaf Edges turning black

If the leaf edges are turning black, maybe a deep purple, on a phal plant, should I be worried? Is this the start of some disease? This is the only leaf that is darkening so far. I've only had it for about a week.

Looks OK to me, when I grew Phallies, I found in the hot bright summers when new leaves grew they often had a purple tinge around the leaf edge. Result of bright light mine were under 70% biscuit coloured shade cloth.
This is often in my greenhouse the result of good growing conditions, nice big plump leaves and in a few months time, plenty of flowers
Cheers

Agree with Ron. Some ancestor of this plant had red underside leaf color. Bright light encourages this trait. Are the flowers of your Phal a red (or variant of the) color? Your plant looks very healthy.

Thanks for putting my fears to rest. I wasn't sure what to think of that color change; and being only on a single leaf made me wonder.

Sorry, but I do not know what color it is. There were no tags. It has 2 flower stems but no flowers, no buds. I got them on a 50% off rack.

As it is the dead of winter here I have it, along with a cattleya I also picked up from the sale rack, sitting in a north-northwest facing window that gets no direct sunlight. Sounds like it is in the right place and is happy.

For your Phalaenopsis I agree. Isn't it great to get a bargain? It must be getting enough light to develop that reddish tint on this leaf. I would advise finding a brighter location for your Cattleya. That plant requires much more light than your Phalaenopsis. Both do need good humidity and warmth.

The way my house sits my choices are NNW or SSE...or the T5HO light over my high tech aquarium. I do have plans to move it to my south facing window. That room is empty to redo the hardwood floors right now though.

Thanks again for your advice.
