can't help with the strain question, but they're definitely looking like something i'd smoke! my guess is that bertha is a different strain if you're still noticing "stretch" growth on her. you may have seen the 40/60 thing i posted (thanks icbh707!) on some other threads, but here's a link anyway. knowledge is (potential) power, after all.

hope that gives you an idea of how much longer you have to wait.

it is possible that rhonda is root-bound, but a transplant could be risky. just recently, an aquaintance of mine transplanted at about 30 days into flower. his buds stopped growing from the shock. trichomes continued changing from clear, to milky, etc., but no more bud growth from then till harvest. just puttin' that out there.

good to see you on LIVE last night too.

stay safe
