Any idea what is wrong here all the others are looking good. Slow release tomato nukes in 5 gal pots. Its been 90+ her with 60% humidity here for 2 weeks. Just startes water 2 x per day.

Heat and low moisture can cause the edges of the tomato leaves to die back, then twist and curl. Hot dry weather may also cause a symptom called physiological leaf roll. This is a self- defense response, where leaves and leaflets curl slightly to prevent further water loss

yup, they look dry kev...are you watering to runoff...if that soil mix is similar for pot meaning pro mix type peat I've found maters don't care for it...

I use Peat mixed 50/50 with Kellogg's Organic potting soil and add 30% perlite and my tomatoes are doing great. I'm having to use a 70/30 Sunshade over my tomatoes and veggies because of the heat.
And no they won't like pure peat moss like Boo said.
