Tomato Black Russian?

That's mostly all true, Christopher, though their advice to spray after you find early symptoms of Early Blight is crook. The only effective spray technique is preventive - before the spores arrive. Once leaves are infected, there's no killing the spores apart from removing infected leaves and destroying them.

Late Blight is a lot, lot less common in domestic gardens. Early Blight is probably the most common domestic fungal problem, along with Septoria Leaf Spot.

My point was only that covering the plants won't protect from infection. Won't even reduce the chances. While damp foliage can be an incubator, the spores will still infect dry foliage. I see it every season. I get zilch rain in summer, have very low humidity, and still end up with Early Blight.

A bit of rain won't hurt the plants. Blight arrives via fungal spores travelling on the breeze. If they're around, they will infect the foliage wet or dry. In other words, covering them from rain won't stop infection.

It's unlikely to be a virus, Derek. More likely frost if there was one around. What state are they in? If not too badly affected, they should recover, though will be a lap behind the healthy ones.

You're better off starting a new thread with a new question, Steven, otherwise your query can get lost.

Are the lumps - pustules - on top of the leaf or underneath? What colour are they? Sounds most likely like a fungal disease.

I've seen it with Dipladenia that either aren't warm enough or have wet roots, either from overwatering or poor drainage.

Any chance of a photo, Lindsay? It's hard to know from a general description. Are they simple spots or can you see a tiny, darker "bullseye" at the centre of the spots?

Tom seedlings will happily live in a 3" pot till they're ready to plant out. No need to pot up.

Low voc paint on terracotta pots

I agree. The advantage of terra cotta is that it "breathes". Much healthier for the plants involved. Painting would have to seal the porous surface.

They'll be fine. As above, the white patch is probably the sun scorching a wet leaf. One or two of my seedlings have the same. Purpling foliage is very very common with seedlings, usually a sign that they need more warmth.

Tomatoes are already flowering

Depends how old they are and how developed they are, Tonks. If they're still bona fide seedlings - not yet ready to plant out - I'd take off the flowers. Let them direct all their energies into establishing themselves. Plenty of time for flowers later.
