And another - Blackish Tomato Leaves.

This is from our toms in a cold 'house, in grow bags, fed & watered as per, well ventilated. It hit Gardener's Delight first, not just the bottom leaves, then went on to several other varieties.

Advice most welcome.

I get that on all my Toms most years - its sort of purple-ish, right? mostly just the bottom leaves.

I think its some sort of vitamin deficiency, but I've tended to ignore it ...
