Tomato pruning help

[Ostrodamus]

TLDR: My tomato plants are crazy overgrown (I think). I need advice on trimming them.

I was gifted 12 tomato plants this season (unknown varieties) and they have grown WILD!! Being a novice, my suspicion is that the overcrowding is causing them to stay on the vine for much longer than they should (perhaps air flow problems?). Admittedly, I don't know that length of time either. I do know that I have clusters of green tomatoes that have been hanging there for close to a month already (if not longer). They are on an auto-drip (calculated) system and get general tomato/veg fertilizer monthly.

Are these needing to be trimmed? If so, how is the best way to do this?

Thank you.

It generally takes 30 days or so once a green tomato has reached full size to ripen.

It appears your plants are indeterminate. Is that correct? People have different opinions on pruning indeterminates. I like to remove all new suckers from them once they get up to about three feet tall. I do this mainly to manage them.

Your plants look healthy but not a lot of fruit and/or blooms showing. If mine, I would give them each a couple of handfuls of Epsom salts sprinkled around the base and water it in.

We always feed our tomatoes with Tomorite. Can you get that in the USA ? https://www.amazon.co.uk/Tomorite-B...939842752-B079TP7V91-&hvexpln=74&gad_source=1
