Auto blue not growing

Hello all
Got a quick question
I know it was probably a little early but I put an Auto Blue Mystic seed in the ground about 4 weeks ago. It took 10 day’s to pop but has been up for 23 days now and is not growing at all. Sorry no pictures but I’ll work on that. It’s only about 2-1/2”-3” tall and only has the three fingered leaf. From what I’ve read I think it’s a PH problem with the soil or water or both. I don’t have a PH meter but have ordered one. It should be hear next week.

Any thoughts?

Thanks

Thanks alot for all your knid responces

did you loosen the soil up before you planted, may be having a difficult time spreading its roots if the soil is too compact.

Does it look yellow? And what kind of ground ? Sounds like roots if not growing at all. And what's you night temps been?
