Hmm federation got a little weird there
Some of those leaves don’t look super happy - getting enough water? Also see some dead foliage in the background - usually best to trim that out. Especially for heirloom tomatoes, they seem to need a lot of prevention with things like septoria.
so I’m not sure what is going on. All 4 tomatoes I have are curly. I am planted in buckets and used purchased potting mix, so possibly too much fertilizer? (haven’t added any beyond what is already in the mix). They don’t look burned though.
Also this particular plant was unhappy because I apparently forgot to drill weep holes in the bottom of its bucket (fixed now).
This bucket is also probably way too small. I got several plants dumped on me and didn’t have any ground prepared or any larger planters.
Good drainage is super crucial.
Now you just have to be patient while you wait for them to ripen…
