I actually looked at your log before posting that comment. You don't need to be a troll when someone is making an observation about something a ton of people do. You're running more than one strain and waiting until the slower seedlings are ready; this is understandable. But those PC were ready to flower a while ago, that's what I'm saying. I've talked to people that were really shocked to have a huge stretch in PC, but waited to flower until their plants were like 13"+ tall. If you have a tall environment it will still work obviously, but with a hearty indica dominant like PC the optimal height is lower (60-80cm for PC).. The advice I see given all the time is to grow single strains (at one time), as they will have similar growth, which would avoid waiting extra weeks to flower/ varied canopy height. Also you're gonna harness the productive potential of the plant more effectively by flowering it short and focusing energy on bud production. So yeah, you're er welcome for the er input.
