If you have plenty of seeds kill the scragglers and re-plant if they are from the same batch,but bear in mind you may be culling the most potent ones,but it will lead to easier grows, yield and quality rarely go hand in hand.
Great advice...I guess the key is patience. At $10 a seed(Ethos Mandarin Sunset), i'd hate to waste them. All these were popped at the same time. View attachment 1275449
