Dropping two seeds into each final pot and cutting the weaker seedling at day seven is a cheap way around the no transplant problem. It costs an extra seed per pot, which adds up with pricey packs, but it beats an empty container sitting under the light for a week while you restart. Whether the trade is worth it depends on pack price and germination history, and the calculator on https://turboautoflowerseeds.com does that sum for you. Pull the loser rather than cut it if roots have not tangled.
