I’m growing five of Bodhi’s Mendo Purps/SSDD right now (along with four of his Big Sur Nigerian x NL2), four weeks into flower, and I totally agree with you, they look like they’re gonna finish really quickly. Last week, I thought they looked like they’d probably be a 60-63 day finisher, but I was in there watering last night and was like,”Gawddamn.... These plants look like they might be ready in eight weeks...” But that’s just the Mendo Purps/SSDD’s. The Nigerian/NL2’s look like they’re gonna take twelve weeks or so.
Anyway, nice grow! Only one of mine is exhibiting any kind of purple right now. Yours look good. That runt might be a little, uh, runty, but you gotta love how it looks! Real purty...
