Is it common to have a pheno every once and a whil...

Totally, a stabilized feminized strain will still show discrepancies between phenos. Be it terps, growth rates, finish times, and even some really cool oddballs, such a a tri-cotyledon germination that had triple axial internodes.. and sometimes, as with the Barney's vanilla kush, of 3 beans popped, one was totally sativa dominate and the other was a typical kush growth habit.. it can really be like a box of chocolates sometimes, never know what little gems you'll end up with. The is why I order 5 seeds or more when I get a new strain... Happy growing
