If its on day 27 it should be in lockdown
why are you candling it?
Veins is a good sign, not moving isn't that concerning since it might be resting
Just leave it alone and give it time
i think Day 1 is 24 hours after they're set, the first day is actually 0, and then after 24 hours it is day 1- so basicaly the first day isn't counted
its best to candle on day 5, or day 7, there should be good signs by then but i don't discard any until day 10 to be sure
