You may note that yellowy speckly appearence of the leaves esp on the right. I believe that is a mild case of chlorosis. https://www.google.com/search?q=maple+chloosis&oq=maple+chloosis&aqs=chrome..69i57j0i13l2j0i5i13i30l7.6616j0j4&sourceid=chrome&ie=UTF-8
This nutrient deficiency is not severe. I do not believe that you need to inject the tree.
Consider a soil analysis or a simple pH meter to guide your work.
Follow the Morton method.
Soil fertilization treatments produce the best results, but are usually the slowest to respond. Soil treatment is best done in early spring through mid-May. For mildly chlorotic trees, fertilize with a nitrogen or nitrogen- and sulfur-based fertilizer. This will provide some acidity for the treatments below.
- Incorporate chelated iron (found in garden centers under various names) into the top two inches of soil. A root feeder may be used, but follow label instructions for rates. Water in well.
- Apply manganese sulfate or iron (ferrous) sulfate at a rate of 0.25 pound per 100 sq.ft., watering in well.
