yahooman,
Yes, what you have is leaf septoria, also known as black leaf spot, or rose leaf spot...
It will spread and cause your foliage to turn yellow and fall off..
It usually starts near the bottom of the plant and works it's way upward...
The good news is, it does not affect the buds themselves.
The bad news is, if all the leaves on your plant fall off, your plant won't live long enough to grow any buds...(or very few smaller buds)
I hope it's not to late, (but that looks pretty bad for this early in the season)
It is a fungal disease and spread by spores...
First, cut off all the really bad infected leaves...and carry them a long way off from your girls to dump them..(best to burn them though)
Second, mix 1 slightly heaping tablespoon of Potassium Bicarbonate and 1 teaspoon of Murphy's Oil Soap to a gallon of water..
put it in your garden sprayer and spray the girls.. Be sure to spray the bottoms of the leaves too...
You probably need more than 1 gallon for a bunch of plants,
so mix accordingly...
Don't spray more often than every 10 days...You will notice if it's working in 2 or 3 days..
This mixture raises the pH level of the surface of the leaves to where the fungus cannot survive.
But don't overdo it because you will get pH burn on the leaves.(but that's not nearly as bad as the septoria...)
Good luck...
PS... do you see this disease on the shrubs and bushes surrounding you hidden garden?
If so, make more mixture and spray them too...
ive done all that you instructed,now time will tell
thank you for the advice!!
