what do you use as a prevention for blossom end rot,reading a few different articles,last year first time ever my tomatoes only 1 plant got the end rot,i know my watering was in good order so calcium was the problem, do i have to buy a special calcium supplement?.
-
You can buy calcium powder or you can make your own... I use egg shells, wash, dry, crush and then blitz in my nutribullet to a powder, then I add it to compost at every potting on stage and also add ½ a handful when planting into their final stations, seems to work for me!
-
You can also supply calcium as gypsum, or as pelleted lawn lime.
Another option is calcium nitrate fertilizer.
-
Over applying high-potash tomato fertilisers, can also cause BO rot - as explained here

Thanks for the replies, i like the egg shell one as i have chickens, i will start collecting today :D.

You could try a milk feed when they start to flower as a calcium supplement. 50/50 milk/water to replace a standard watering.
