i'll have to think about that os...talking out loud, no one had herms from the f1's that were tested pretty extensive that i heard of, so we can rule that out. i've made polys also with those, and have already ran those, (and smoked them), and no funny biz there either...found the pp flavor dominated whatever it touched; hoosier daddy x pp, pure afghan x pp, even made and ran my own f2's...(been a busy boy)...
how far out in flower did you run the f2's rosebud? maybe we can talk this thru to a late end run expression? we figured 9 weeks average was where we were chopping her, both f1's and (my f2's)...
only issue i ever really had was outdoors. they loaded up on mold late in the season here before rains came...
only thing i can think of atm os, were you running the f2 mom in same flower room, after she was pollenated, with your blue dreams? if so, was there any funny biz going down with those at some point?
sorry that happened to you rosebud. were there any others in flower running with them?
