Could you possibly give us some idea of what you have? Age, rootstock, in ground or container; if in ground, do you know what the pH or your soil and/or water is? How old is the tree? With a few "clues" like that, maybe we could help you.

John, thank you for taking the time to respond.

Meyer Lemon, container in the 511 mix. Originally a cutting I rooted myself. For the most part, the entire small tree looks very healthy except for a couple leaves from the top new growth which is less then 2 months old. Not all the new growth looks this way, most looks great. I just wanted to share this and possibly avoid an issue now rather then when it becomes a bigger problem. The tree gets watered 2-3 times a week with 1 tbsp of FP per Gallon of water at every watering

Johnmerr hit it right on the nose. It is exactly what John wrote. The situation that your tree is showing is very common this time of year. If the fertilizer you are using has all the trace minerals your tree should be fine.

A further note... can you check the pH of your water? If it is over 7; try adding a little vinegar with your FP; high pH is one of the main causes of Mn deficiency, as it is difficult for the plant to absorb it when the pH is high and/or the soil is cool. Last... if your tree is in a clay/terracotta pot, evaporation through the sides, cools the soil

Thank you John and silica. I will test the PH of my water + fertilizer and see if it needs any adjustment.
