Tomatoes stopped growing

[ConwyC]

Originally came here to pH to ask a car question, but was not allowed to post. As I am registered....

Planted five tomato plants in 40ltr containers in my conservatory, they started off really well, the plants grow thick and tall each producing about six beef tomatoes on the lower part of the plant, a couple were 700g! Then stopped. I hand pollinated them after nothing happening for a few weeks and I got quite a few new growing fruit. A few weeks ago the growth come to a halt again,

I feed them, give them fish, bone and something else, I even gave them used coffee and banana peel

Any advice?

I am being allowed to post once more, hurray,

Thanks for your replies, not the only one in this position then.

They could be a "determinate" variety.

According to the seed packet they are indeterminate, 75 day variety, what does the 75 days refer to anyone?

Unlikely to be the issue but we’re you nipping off the intermediate shoots?

you mean the suckers, yes I have been pulling them off, they are growing just fine.

The one thing tomatoes need above all else is consistency: consistent temperature, light, and water.

Has anything changed? Has the temperature fallen, or gone very high?

well they are right in the window and the temp although varied because of the weather has not gone down below 20C in the conservatory. even on Friday when it was raining all day when I got home at midnight it was still 20.

watering depends on the weather currently every other day but the day it was hot I watered every day.

I quadrupled their feed yesterday, so they might be dead now, I'll see when I get up in a bit
