Second Grow Ever

Just finished the 2nd week of flowering, starting the 3rd week. Flowers have started to become much more noticeable. Trying to train the plants a bit, using wire, to allow more light into the middle of the plant, where there is a lot of stuff in shadows. With the current diameter of the branches, it's probably too late to do that though.. The smell is starting to get stronger at seemingly random times. The smell is similar to burning rubber or burning plastic.
