I have a seed packet for this plant that says to sow seed thinly because crowding will lead to weak leggy seedlings. You situation is exactly what I had last year!
You might want to thin a bunch of them right now and let the stronger ones grow a little stem diameter before planting out, if there are any that haven't gotten too leggy.

I thined out about 50 of them and planted each seedling in its own little container.I still keep the rest in the main pot' to transplant later.
Most of the seedlings went into a shock and drooped.A few didn't make it.For the rest I supported then with bamboo sticks and watered daily. They are in full sun (about 6 hours) and so far seem to be doing very well.
I wait for the stems to get thicker before transplanting them to the garden soil.
