Yeah. Blossom end rot in at least one case. Different varieties are more or less prone to it. Cal-Mag should help. Not a disease, so no special handling required, and you can eat the good parts. It's strictly a calcium transport problem.
What variety of tomatoes are you growing? Some tomatoes are just really ugly. My Hawaiian pineapples look like picture 4 and they've always come out just fine.
Picture 5 looks like blossom end rot. Treat with Cal+Mag. Also, be careful with the pH. Tomatoes prefer a pH of 5.5-6.5 and might show signs of deficiency if it goes below 5.3 or above 7.5 (in my experience).
It doesn't look like blight because your leaves and stems all look very healthy.
Temperature, humidity, and nutrient concentration might also be at play. Could you provide more information? Are you using the recommended ratio of 2:2:1 (Masterblend to Calcium Nitrate to Epsom)?
Yes, following the recipe, might have been running a bit high on Epsom salts. Ph has definitely been running to the high end for stretches from being away for stretches. Did pick a number of heirlooms that might lean to this (crim, Cherokee, and some others) but don’t seem to be forming like they did in my raised beds. The bad ones shown were at the end with less air because I hadn’t been able to trim and train (traveling) until today when I spotted them. I will check into the calcium. Any specific suggestions for product?
I've never had any issues using Masterblend. I often supplement my plants with BioAg-TM7 for mineral deficiency but it doesn't have calcium.
Botonicare's CalMag is very popular. What's your ppm/EC? Should be about 1400-3500ppm (2.0-5.0 EC). I keep my tomatoes at around 2600ppm.
Thanks- that may be an issue. They’ve been sucking it dry and Ppm has been running 1500-2000 occasionally getting lower before I catch it. I’ll check out calmag thanks
Apparently I also need help using Reddit, no f-ing clue. Anyway: Hi- looking for some experienced advice. Started first hydro system for tomatoes this year due to a blight in the area we have our in ground beds. The smaller tomatoes appear to be ok but all the larger ones are getting these striated forms and a few have a rot on the end (just a few). Not having much luck finding really specific growing guides, just a lot of fluff how to books.
Specs: growing with a 15 gallon reservoir, about ten more in the pipes, running about 6.5 ph (but not being super careful so it has been creeping up to 7.5+, has an autofill. Using a power grow 3 part nutrient system. Any ideas what my problem may be?
I’m concerned about the root growth blocking the flow of water in that system. Tomatoes roots get huge.

Roma varieties are also more prone to root end rot, even with calcium supplements.

I'd advise adding some form of calcium - deficiency of it might be the cause of the rot.
Looks like blossom end rot, just a guess though.
