indoor tomato not growing

Are the flowers dropping before the fruit sets?
How big are the fruits getting before they stop?

bigger than a golf ball when they stop and some flowers fell and some quarter sized toms just stoped

could be cold temps. Often fruit won't set in hot climate plants until the temp is right.
I had same problems with my egg plant, after a couple degrees raised temp they grew to maturity
most tomatoes are day neutral so nutrients wont cause flowering but it will help with better fruit.

over fert too much salt in the form of food will cause blossom end rot and slow growth

maybe they are suposse to be small? there is possibility that they were labeled wrong.

roma is the smallest tomato ive come across. but they are still green. temps in the 40's at night.

your indoor temps are that low? they have grape and cherry tomatoes. i have some right now i got at the farmers market that could be confused with grapes. some are also green. but i like the yellowish and purplish ones the best out of this bunch my favorite are sun gold.

i wish i could like to the taste to eat them. i need ketchup for my meat-loaf. so that's why there is that. my spinach tastes good. i still need the ketchup for more though i know it. have you made anything with yours? how have you grown yours? any of you also?
