Suzy, is the leaf yellow or white?

Some leaves are white when plant is lacking chlorophyll, and/or variegated plants.

I've noticed 'some' of my variegated plants' foliage grow white leaves when placed in shade, others in bright light.

There are many reasons a leaf/ves yellow. If your leaf is yellow....

Sometimes leaves yellow for the simple reason....season change. Of course, there are other reasons such as under/over-watering...and then some.

See how your citrus does in the future. If a couple leaves yellow and drop, no biggie..if they yellow and drop on a daily basis, there's a problem. Don't want to get in that now...see what happens.

I tried expanding your photo. It opened, but pic is the same size as photo on this thread. lol. Toni

Looks like and inverted leaf, probably wind related; I wouldn't stress about it.

Thank you Both. Good to know Toni. John I inspected the leaf and you are correct. Sorry about that. I should have looked at it better before. My 8 month old meyer is great and growing.
