If you're looking to get some of those purple phenos like the ones you got your seeds from...Run one more generation..(probanly a recessive trait) Pop a bunch of those seeds..Grab you're favorite male and favorite female...Breed them again...I'm guessing 1 in 4 resulting seeds will now give you that purple pheno again that your looking for..Once you find that purple pheno, either self it with Colloidal Silver...or pop a bunch of beans in hopes of getting a purple male and purple female to stabilize.
Nice work..
