Spider Farmer Spooky Bonsai Bonanza

Gdp bonsai has lots of new rich green foliage, but some deficiencies showing. Possibly magnesium so increasing calmg. Also concerned about powdery mildew since my flowering blueberry under the other light seems to have a little. Treating both with a 0.3% hydrogen peroxide spray daily but doesn't seem to help very much. Will increase concentration to 0.6% and see if that does the trick without hurting the leaves.
