Not using growlights (and the weather has been cloudy).
Is it too early to introduce her to the outside in cloudy weather and very, very mild wind? Photone app says ~2000-2500 ppfd.
Anything else I can do to help her?
Thanks
Your readings seems to be off or you do have more than enough light for your seedling.
I wouldn't hurry to put her outside. It's too tiny, too delicate and it receives enough light for its age.
looks like it's gotten a bit too much light, yes...
slowly introduce.. keep it in a more shaded area at first. watch resulting internode lengths as a guide. if it's tight and runty-looking, it's too much light.
Seedlings are probably best started in the shade. Helps protect not only from intense light but also offers a little cover in case of heavy rains that could flood a young seedling.
