I did same. Don't overwater. Watch your PH...you can get that on the web...can't remember what it is. Very weak fertilizer if any. Outside everything is fine with them. Once you have to bring them in, things seem to change. They will need as much direct sun or light that you can give them and warm temps. Be very careful not to bump or mess with any new growth. Prone to drop at slightest touch. If this is environmental, I don't know how to correct at this point. Very slow growing. I'm in Ohio and my seedlings are 1 yr. I have 3 left anywhere from 6 inches to about 10 inches. They seem to transplant fine. Just be careful. Good luck.
