No, I've never had any nanas on Ace plants and I didn't take clones. I killed the Malawi males from that grow on sight and made only F1 beans with the Blueberry, which actually throw purple phenos (about 1 in 4).I don't reckon you did any S1 seeds from that female, did you?
The offspring of the cross are generally robust, vigorous, tall and branchy, and the buds are big, dense and heavy, flowering in 65-75 days and the high THC chemotype plants are super potent. But the purple pheno's are smaller in every way and are very mild smoke. Many of the rest smoke similarly. While it has been a fun experiment I have to say the Purple Malawi is not the best breeding tool if you are seeking potency from your smoke.
I definitely plan on making more Malawi crosses (C99 for sure) but will look for a nice green fruity pheno next time. I've had one of those before, it grew with no issues, had excellent structure and yield and had very good potency with an exceptional high that made you feel good about yourself and your place in the universe.
