Sour Sundae - Indoor - SF4000

There is very little to do with the plants, they are getting fatter by the day and frostier by the day. I found out I was giving them way too much nutrient so I started giving them 0.4 EC less (its still a work in progress). The lights are still on 85%. It is starting to smell more and more sour and there is also a fresh lemon smell coming from it now.
