Tomatoes - a progress report

My tomatoes are looking very strong now. Many of them are about three feet tall, and some of them have their first flowers, though no fruit has set yet.

I have started feeding them now, because they have been in those pots for a few weeks now and the nutrients in the compost will have been considerably depleted. I use "Tomorite" proprietary tomato-food, though later in the year I will try to make some home-made Comfrey Tea (although my comfrey is looking very sparse this year, so it probably won't amount to much!)

This is a flower on "Cherokee Purple". It's a very complex flower for a tomato - almost "double".

Do you see how the upper leaves of the plant in the photo below are curled inwards, almost bunched-up? I used to be worried when this happened, but I researched it and found that this happens when the nights are too cold for the plant's comfort. We humans do the same when we are cold: we wrap our arms around ourselves and clench them tightly. No real harm is done, and the plant will unclench in due course.
