My watermelons started out gorgeous and healthy. But now there is this sticky looking web substance and tiny blackish bugs on one side of the patch. Are these mites? What can I do to save the plant? Fruit grows but only to shrivel up and fall off or turn blackish- purple.can someone please help?

You have more than one issue here... First... Let's address the mites. These will destroy your crop... fast! Now from here it gets tricky. There is a product that has saved my you-know-what several times... It is called Foxfarm's Force of Nature miticide. It is all natural, and very concentrated. 1/4 oz. to a bottle of water, and spray it all over. soak it... Now You appear to have another issue... Purple usually indicates to me a phosphorus deficiency... This is going to sound crazy but take a half bottle of the small gatorade (your choice of flavor lol) and pour it in. go ahead, laugh it up. ;) Now, lastly, you should think about resolving a pH issue that might be causing your deficiency... I would fix that with a product called Dolomitic lime (I use Agri-pel, I Live in Tennessee and a 40 lb bad costs me about 5 dollars. I handful per gallon of soil, or if it is in ground... about 5 small handfuls should do it.
