Hi all. First off let me to say a big thank you for a great forum and amazing help and comments from everyone here. So many times in the past you guys have been of great help in situations where I was lost as to what I should be doing.
On to my question.
The pictures included show some brown substance on the Leaves. I did have powdery mildew and did have an issue with it. It was quite a serious Outbreak. I had to throw away several plants, and I used apple cider vinegar to spray the plants very lightly.
The pictures you see here are some of the remaining plants but I want to make sure whether or not this is just a result of the major powdery mildew outbreak, or whether I should be looking for something else.
So that is the first question, namely, is this something other than powdery mildew?
The second question is: how regularly may I use the apple cider vinegar now that I am fighting a powdery mildew Outbreak? I mix 2 teaspoons with 1 litre of water and spray very lightly.
Thanks in advance for all the input, and thanks again to all for many, many previous assistances.
