hi thanks. very helpful link.

[Bud]

spray it with soap/cinnamon mix:

10 drops dish soap
1/2 teaspoon cinnamon extract (find it in the baking aisle of the supermarket)
2 cups tepid water

shake well in a spray bottle and spray the whole plant including the roots until it is soaked wet

do this every other day until you see the leaves have cleaned up a bit....

Just make sure to avoid getting cinnamon on the roots.

Cinnamon has a phytochemical called cinnamaldehyde that is considered to have antiseptic properties, and it is also known to be a growth inhibitor.
