One out of four sprouts in my tent isn't developing any leaves or roots. This are autos. The rest is already developing their fourth leave. Can I just replace this by a fresh seed and germinate in the netpot. It's going to be behind the other ones but would this be an issue?

If this is a Rdwc you will be giving nutes before it needs them as a seedling. I had a seedling missfire during the planting and relaunched a new seed. Then I had plants 3 weeks apart with different light and nutes requirments.
Did not work out for me
