Powdery Mildew? Not sure!
IÃ¢ÂÂm a newbie gardener, this is my first year and IÃ¢ÂÂd like to seek the advice or an explanation for the following potential issue I have with my zucchini plant. I noticed a white substance growing from the edge of the leaf towards the center of the leaf. IÃ¢ÂÂve heard of powdery mildew, but from the pictures IÃ¢ÂÂve seen online, PM is more of a spot-like formation. Anyway, IÃ¢ÂÂm not sure what I have on my zucchinisÃ¯Â¿Â½Ã¯Â¿Â½"or if itÃ¢ÂÂs normal. IÃ¢ÂÂve posted a picture, and IÃ¢ÂÂd appreciate a possible explanation from some of the more experienced gardeners here.
Thanks in advance.
