Many times the extra teas cause an imbalance in the feed and that locks out phosphorus etc. Too much molasses has detrimental effects. Just my input, I'm not an expert.
Autos can be difficult to get pollen from. If you are short on seeds, it would be easier to get some. They can be sprayed after a couple weeks of growth, but may require more time and money than just buying seeds.GL
Just dry in a cool place with some humidity. A small hygrometer can be gotten for a few dollars. Aim for 60 rh when drying and as cool as you can get .Don't put a fan directly on them. It should take 7-10 days to dry. Once the tiny leaves are crunchy and the bud springs back when you squeeze it...
Uhh OK, you could try adding some more soil up to just below the tops, And only water one side of the seedling and next time water the other side. No added nutrients needed for tiny seedlings in soil.
