I see this is a few month old, but I am now growing BB#3.....YOU WOULD THINK, that since the #3 is a pheno of 5 DIFFERENT phenos of the ORIGINAL BB, That they would ALL exhibit very similar traits...NOT SO, I see 2 distinct phenos when growing BB#3....ALSO, every breeder has THEIR OWN VERSION of it....They use THEIR strawberry diesel and THEIR OG for the cross, pick out what they think best represents the #3 pheno and 'Selfie' it ( or backcross if your more familiar with that term...The best is Strawberry Diesel crossed with the GHOST OG....
ANYWAYS, your just seeing what I have seen with #3's....if you look at the bud structure, your 2 outside plants (the ones you dubbed the same) ARE the same pheno WITHIN the #3 pheno group...The cntr plant has conical shaped buds with that distinct taper at the top...the others are very rounded.....ALL LOOKING GOOD...the yellowing is either a late life NATURAL yellowing, or, that pheno is just a hungrier plant...Nothing to worry about that far into flower....In fact, if it is just a hungrier pheno, having it yellow out at the end us a sign that ALL stored and/or residual nutes are depleted....THIS WILL HELP INSURE SWEET BUDS....Yellow like that is most welcome just prior to harvest....The high and THC totals will vary btwn that plant and the other two...CHOICES ARE FUN....It might be the one you should be cloning!!!....regards, YT
