looks like sunburn; maybe you should give it some shade during the hottest part of the warmest days, but don't move it; Meyers are very sensitive to light changes.

I was thinking that was a possibility, but then I talked myself out of it since I figured lemon trees wanted all the sun they could get. Who knew that citrus wouldn't be able to take a Buffalo summer? I'm certainly no expert, but your explanation makes sense if the plant is sensitive. thank you

Was any thing sprayed on the leaves? I ask because the damage is limited to the edges of the leaves, which is where damage due to chemicals would be expected.

well I did spray the plant about 4 weeks ago with iron chelate. I thought the plant had chlorosis. You can kinda see the darker green veins and yellowish leaves. I stopped spraying since it didn't seem to work, I thought I followed the instructions but perhaps not

That may have caused the damage. The nutritional problem (chlorosis) may be due to the soil mix you are using and/or the fertilizer.

Foliage Pro 9-3-6 (FP) is a fertilizer
that contains all of the nutrients that citrus trees require. Each
time you have to water, add 1 Tsp. of FP /gal of water and use that instead of
pure water. Get a cheap pH testing kit - the kind
used to test the pH of swimming pool or aquarium water. If your tap water is
above pH 6.5, add enough vinegar to adjust it to about pH 6.5. You will only
have to add give or take 1 Tb/gal. So, you will be watering with a mix of
vinegar and Foliage Pro every time the tree needs water.

When repotting into a different kind of
soil mix, remove the old soil mix by dunking the root ball in and out of water.
You may have to use a garden hose to gently force the old soil off.

This is what I use:

· 5
parts pine bark mulch (remove ½” pieces through 1/2 inch screen)

(Some people use Repti Bark instead of
mulch. This does not require screening but may require more frequent watering.)
Be sure to soak the bark overnight.

· 1
part sphagnum peat

· 1
part perlite (coarse, if you can get it)

· 1 Tb garden
lime /gal 5-1-1 mix (measure the 5-1-1 mix)

· Osmocote
plus (follow manufacturer’s instructions

·
Moisten well and wait at least 2 days before using
