how come the first 10 seeds that came out of one batch all turned out identical to the mother the last time i selfed one branch and this time the 10 seeds i kept are all different. how come phenotypes skip a generation? its santa cruz blue dream btw.

This is Mendellian genetics 101 (and although they are involved its a little more complicated than "recessive genes").

Making this super-simple, if you cross two inbred lines, the F1 generation will all put out similar plants.
Cross the F1s and the F2s will throw out every possible phenotype and variety seen in both parents.

Expressing this in conventional genetic nomenclature, suppose your parents are AABBCC and aabbcc. (We're only looking at three genes here).

Cross them and ALL the of offspring will be AaBbCc. . .one "pheno".

Cross two of THOSE and now you'll potentially get

AABBCC, AaBBCC, aaBBCC, AABbCC, AaBbCC, aaBbCC, AAbbCC, AabbCC, aabbCC,
AABBCc, AaBBCc, aaBBCc, AABbCc, AaBbCc, aaBbCc, AAbbCc, AabbCc, aabbCc,
AABBcc, AaBBcc, aaBBCc, AABbcc, AaBbcc, aaBbcc, AAbbcc, Aabbcc, and aabbcc.

That's potentially 24 different GENOtypes, which could be up to 24 different PHENOtypes (but probably isn't since with dominant genes, for example, Aa will look the same as AA).

And we're only looking at THREE traits! Imagine how many phenos you could see if you're looking at 10 traits, etc.
