Hi, the lemon tree leaf has dark spots and curly underneath

I don't think you have too much to worry about with your lemon tree. There may have been some thrips present on the plant at a particular time which could cause the leaf to curl. The overall foliage looks reasonably healthy. There is a little yellowing in the leaves but this can easily be rectified by fertilising with a good quality citrus food such as Thrive Natural Pelletised Plant Food For Fruit And Citrus in spring. The tree will begin to put on new growth at this point and will certainly benefit from receiving those nutrients.
