Oh dear... I think your way off the calendar

Plant March to mid-August or July or August for winter varieties.

If they're in your house, they're way too warm. I find that in summer, even outside it gets too warm for them.

Wait until later, if you have no cool greenhouse, don't grow them in the house, wait a little longer and direct sow them outside.

This is how I like to do mine for slug free radish:
