Hey guys just a quick question, I noticed a few irregular spots that have appeared to have dried up. The affected areas crumble when I lightly squeeze them so theyre completely dry. This had happened with a couple of the leaf edges as well. My tomatoes are still young, only about 3 feet high. They were sprayed with a copper based fungicide about a week ago. Would this be a disease or just a bit of damage from the fungicide? Please let it not be late blight... :( To add, its been fairly hot here for the past coupt of days.. Reaching 30 degrees celcius..

thanks :)
