Why are White Sapote leaves twisting?

[LeeAnn]

Hi All, Does anyone who is growing white sapote trees happen to know what causes white sapote tree leaves to twist almost like mango leaves do it is deficient in a nutrient? The sapote tree is growing in a large clay container with good drainage in sunny spot. Not all leaves are twisting; for the most part they look green and healthy. The tree is seedling grown since 2015 and is now about 10 feet tall. I have read that it loses its leaves in June, but that is a few months from now. This is my my first post and i am not sure if this is the correct forum for my question, so please bear with me as i am in learning stage! If there is no cause for concern, i am hoping for reassurance that maybe it is just the cold at this time? Thank you All!
