Brown Leaves on Young Elderberry Bushes

Question

I recently planted 6 young elderberry bushes (different types – 6 feet apart) and the white and yellow flowering plants are suffering from discoloration of the leaves (brown/dark yellow). The dark leaf variety doesn’t seem to be affected. We live on a hill and it can be quite windy at times. I water them once per week but more in very dry weather. Any ideas on what can I do?
