I have 2 potted avocado trees that we bought a few months ago. One is Hass and the other is Sir Prize. I am in zone 9b California.

We repotted both trees into large pots a few weeks ago (the pots are about 24" across). The Sir Prize has been looking great, but the Hass took a turn for the worst shortly after repotting. It has dropped many of its leaves.

Today I noticed many of the remaining leaves have a very distinct discoloration from the tip upward. Can anyone tell me what might cause this?

thank you!
