hibiscus plant is potted in very large pot with miracle gro soil...watered daily...getting
miracle gro liquid feed once a week...appears to be very healthy, now has dozens of
buds and is beginning to bloom beautifully....but has begun to have lots of yellow leaves that are slightly spotted with tiny dark spots..and the yellowing leaves are shriveling up and falling off plant. Every day there are more and more yellowing leaves.
What can I do to correct this?
