Growing Winter Savory from seed can be tricky. Ensure you're using a well-draining seed starting mix to avoid waterlogging. Overwatering can lead to damping-off, so try bottom watering to keep the topsoil dry. Adjust your grow lights to be a few inches above the seedlings and keep them on for about 14-16 hours a day. Avoid fertilizing until the second set of true leaves appears, and even then, use a half-strength solution sparingly. Good air circulation is crucial to prevent fungal issues, and maintaining a steady temperature around 70°F helps. Remember to acclimate seedlings gradually to outdoor conditions. Also, check that your seeds are fresh and from a reliable source. Keep tweaking these factors until you find the right balance for your setup. Good luck!
