Kelli what do you fertilize with? Citrus are heavy feeders your tree definitely looks like it’s lacking in something By the looks of those dark veins and yellowing everywhere in between. Key limes are also notoriously abundant producers so something is going on with your tree. Hopefully someone with more experience on fertilizer and nutrient deficiencies chimes in. Do you Plant in ground or in pot?

The tree is showing either a zinc deficiency or a manganese deficiency. Both deficiencies show similar symptoms of green veins WITH dark green borders along the sides of the vein. By looking at Kelli's picture I cannot determine the size of the leaves. If it is a manganese deficiency the leaves are normal in size for the cultivar, but if it is a zinc deficiency the leaves will be smaller than normal size. Applying a zinc supplement (zinc sulfate), or a manganese supplement (manganese sulfate or manganese nitrate) will quickly correct the deficiency. Both corrective supplements can be applied either by a foliar spray, or through the roots. With a Manganese deficiency, many times the tree will correct it on its own.

It’s planted in the ground and I just use general citrus tree shake fertilizer from Home Depot.

Citrus Leaf Miner

Citrus Leaf Miners

LLO where did you come up with your picture. Looking at the leaves of Kelli's tree in her first picture, I do not see any sign of leaf miner. tunnels.

her 2nd pic has tons of leaf miners.

Her first picture didn't show any miner. The second picture was covered and third picture might have some but not clear enough. The photo I used was an image titled the Garden Guy Hawaii: Citrus Leaf-miner. It was a closer match than anything I could find on multiple citrus databases. I am sure with leaf miner damage there would all sorts of nutrient issues as the damage progresses.

I did not see that by clicking on her original picture that it would bring up additional pics.

use some type insecticidal soap to get rid of them

I have this going on. It's a young plant with no leaf miner. I fertilized and hope that helps. ?

insecticidal soap I will kill the leaf miner and the fertilizer will help it recover from the damage

I use both dry and liquid fertilizers. I think the dry ones only work as they get wet and dissolve. Your tree needs some liquid fertilizer now.

Lemon, you have to click the "more" button at the bottom of the post to see more photos.

I don't belive insecticidal soap is effective for leaf miners, nor does it help in recovery

If you are not using a citrus fertilizer that contains micros, you will not be able to correct a nutrient deficiency. You can apply micro nutrients as a separate product if it is not in your fertilizer.

It definitely has leaf miners -I’ve noticed since I last posted -I’ve been spraying weekly with Neem oil and also added liquid zinc but I haven’t seen any change.

Neem Oil will do absolutely nothing to leaf miners.

Once you see damage from Citrus leaf miners, it's too late.
