Is this Powdery Mildew or other problem?
My plants have recently been going downhill. Weather has been really hot and dry (several days of 100+) for a few weeks and then cooled off a little (low 90's) with an abundance of rain from afternoon thunderstorms. This all started during the hottest weather. I was watering everyday via drip hoses.
Some plants are much worse than others and have lost nearly all leaves. Other plants still have all the leaves but have a white coating on them. I suspect this to be powdery mildew from some research I did online, however would like confirmation and the best way to get rid of it! Pics at the link below.
When we got a bunch of rain many of the tomatoes split and a good deal have been rotting on the vine. Not sure if this is related to the above or a seperate problem?
