I grew a few autos outdoors last summer and was told that it was not a good idea to transplant them. Directly plant the germinated seed into the final pot. Seems like you are trying too hard. Maria is a weed, sometimes very finicky, but still a weed. Put some good balanced soil in a pot and let it do its thing. Read alot. I'm new here too but have been reading/lurking for almost a year.
