Autopot - Jack Herrer and Power Plant

Girls are growing fast, I started adding BioBizz fertilizers One of the plants has big yellowish spots on leaves right from the beginning, new leaves are growing healthy so I quess it wont be a problem. Right plant on the front is growing a bit faster so I'm arleady topping it on 4th node, the others have to wait until next week Lamp power at 75% and will stay that way for the next 2 weeks, after that switch them to 12/12 Water Ph 6.5
