Hey there AKmike, wow, you have the sour bubble. From what I read that is the "ONE"! Would love to get my hands on that one someday. The sour grape seeds I popped contained a few phenos... It seems that I kept one that has with a tight purple little knot forming up at it's bud sites ten days after 12/12 and continues with the purple look into maturity, the fan leaves and secondary leaves on the buds remain shiny and waxy dark green though.
The other pheno is more light green with tints of pinkish/purple hues but overall has the bright rust colored pistils when mature. I was thinking the non-purple pheno I have leans more towards the SB in the cross. It has more rounded shaped buds. Here is a pic of the non-purple pheno I have...wonder if it looks like something you have ? Both are super frosty. Do you think your SG is as potent as your SB? Do you feel SB would yield on average more in soil than SG?
