I watched @Tonygreen grow show whilst he made these beans and he said 70 days was the spot for these if I’m not mistaken. Tagged him so he could maybe chime in.
She builds flower slower and bulks up hard later. If you chop at 8 you miss the final swell, new growers might think shes doing nothing at 4 5 then think shes done at 8. A lot happens 7-9 weeks imho. Most of us pull her 63-70 after final late swell.
^As he put it.^
