I will be blunt here and say start again. Put seeds outside in deep pots of multi purpose compost. 5 to a 1 litre pot is quite suitable.
Put them in a coldframe, cheap plastic greenhouse or something along those lines.
They should germinate within 2 weeks and grow much stronger than on a windowsill.
They can stay outside all Winter, just make sure to keep them frost free.
