In my opinion, you can.
Stop watering, put the pots out from water, in a place with plenty of light but no sun, if you do not want to burn them. Put them in a place with plenty of air also. Wind (not too much) is fine too.
Let the soil dry out (now you can see there is too much water at the bottom, and the ground is wet).
Use the handle of a metal spoon or a little stick to offset the earth from the pot and circulate more air.
Plants become so when they have too little light and too much water, in relation to light. Now you need to do the opposite.
When the soil is almost completely dry, carefully observe your seedlings. Add a few drops of water when you see the slightest sign of thirst.
The purpose is to ensure that the plant taking color and snack new leaves, without growing in height too much.
It is a very very delicate operation and requires your full attention.
