I recently got two avocado trees. Waiting for them to get acclimated before I plant it. But one tree is turning dull. The leaves are somewhat folded, rough and yellow tint. Even the branches turning bit yellow. on the other hand the other tree lively green, flat, leathery, shinny. Though same size but next to each other two look like two different species!
I know turning leaves yellow seasonally is ok for avocado. But when i see them side by side, i can't help but to wonder if something is wrong with it. Please let me know if anyone has any idea. or have seen something similar

on the left green one is Joey and on the right yellow one is Lila
