Wow, Terri, thanks for that source. I've looked for that kind of information for years with no luck! I'm surprised at some of the things that are prohibited.

I'm going to say Thanks for that info toooooooo,
Terryyyyyyy...
Nice....

Here's a link for the OMRI products list of approved or restricted materials. (over 1300 products)

Synthetic magnesium sulfate products are restricted, but the 2 non-synthetic magnesium sulfate products are approved.

Wow, more great information, Terry! That's just terrific! Thanks again!

Ron Juftes at Seven Springs Farm got back to me and confirmed what I had already found out. Magnesium Sulfate is permitted by the NOP. (National Organic Program) If anyone is interested, here is his catalog . He has all sorts of organic supplements and supplies (but no epsom salts) There is also an e-mail address in case you would like a hard copy of the catalog.

A good way to do the eggshells is to just whizz them in a blender with a little water. I mix a handfull of powdered limestone in the tomato holes and am not bothered with BMR

Gerry, I'm in Encinitas, what part of San Diego County are you?
I planted a Celebrity tomato in a large pot in January. It's been slow but has blossoms now.
Comfrey, I love your name ! I used to grow comfrey and loved eating the young leaves and in salads and sandwiches. I miss comfrey, can't get it in the garden stores anymore.

I don't have chickens, still fighting blossom end rot too. Indoor with an HPS 400w, I ameliorated soil adding compost and whatever I can find. Seems easier to manage but still here.
Good trick to see in advance it will appear is checking the leafs. If they break making a little noise, feeling something hard cracking denotes there is too much food in the leaves, calcium is not necessarly missing, but mostly going to the leaves instead of the fruits. I've read in a few places and when I cut half of the leaves, it helps, but not definitely.
I'm starting to think I have to live with for some time at least until I find to manage it.
At least removing them helps the next ones, and removing the black end, the small green tomatoes are a consolation to cook with.

I love cooking with green tomatoes too !
Very interesting information, Fredix !

Fredix,
You don't happen to have a picture of the
tomato plant, pot, soil, lighting, etc... do you??
That would be a big help for us to help you figure out what's going on with your plant..

I would be glad to take a few pictures but have only a cheap webcam, not good enough.
Actually, apart from the other plants in soil, I'm trying 3 plants in a hydroponic box with automatic watering. Two fruits appeared since a couple of days and they are just fine. Crossing my fingers. If they keep okay, watering seems the difficulty for indoor tomatoes.
Maybe it is the variety too. My first plants were an ancient variety, maybe they are more delicate.
