Master kush 4x4 grow

Ok so at first I thought there was probably atleast one plant in this tent that wasn't actually master kush (Rocket seeds, who owns sunwest genetics has been accused of switching out popular seeds with less popular ones to get rid of old stock in the past. I've actually had a few questionable strains from them myself). The one in the back right corner has dark pink buds and purple/pink leaves. Front two look the same and the last one in the back left corner kind of looks like the front two but has different looking leaves.... I put the fan on top of a few pots to get it up a bit higher. I adjusted the Co2 pan so that it's blowing the Co2 up a bit higher. This is the last week of Co2 before I stop, no point in using Co2 when the buds have maxed out in size. Well that's all growmies peace ✌️
