Zone9B. Seeded Thai Dragon in paper towels then put sprouts into cups and small containers. Seedlings growing well but tall and leaves are at least 2-3 inch apart. Every YouTube videos and box store seedlings I come across has seedlings with dark green stalks and not as tall. I have not fertilize at all. I have seedlings under filtered sunlight with at least 8 hours. I know I started late in August but just curious what is deficient that my seedlings are tall and lank compare to other pepper plants? I know they are healthy and growing but stalks are not dark green. Any ideas? Thank you.
