Maybe consider an organic liquid fertilizer mix.

Maybe if it is totally air tight. You are really stacking the odds up against yourself. It is recommended to start planting seeds in Oct/Nov in cool/mountain NZ and you are trying to grow them in winter. More chance of a good crop when the conditions are with you than against you.

I want to plant tomatoes in containers due to know space in my backyard. What size container can I use and what nutrients should I feed my tomato plants. Also what fertilizer can be used. Regards Dennis

My daughter recommends a big container, about 30+ liters. A general all round garden fertiliser, make sure you mix about 2-3 handfuls into the soil before you put the soil in the container.

You are probably right about it being too hot. If they are in pots try moving them to get some shade earlier or later in the day. If they are in pots maybe try a bigger pot size. It might help to dissipate heat better with more evaporation longer water retention in the deepest part of the pot.

I just pull mine for the same reason. Is too hot to fruit. When the flower form the sun burn it. And the rain doesn't help much. If you are able to move it under a roof and keep it with sunlight, you may hold on until it gets cooler. It will produce then. Also it is time to start sowing tomatoes seeds indoor or in shade. Good luck!
