Purps OG, Wi-Fi OG and OG kush in 1 room

The EC is already back at 1.3, the plants handle it very good and it seems like the never had a nutrient lockout. The Purps already has a lot of brown pistils and i think this one will finish way faster than the rest, but i'm not really sure about it since i had this before and at the last weeks the buds are more than doubled in size. so lets see what the last week will do 👍
