Hi there! I just noticed today that my sungold tomato plant has all these dark spots developing on its leaves, all across the plant (even on some of the younger leaves). These seem to have almost appeared overnight, which is worrying me!
Any idea what could be causing this? (This is my first time growing tomatoes and I’ve been loving it, so I’m hoping it’s not something too life-threatening for my plant)
Thank you in advance for any advice!
