Girl Scout Cookie Week 6 of Flower Problems?

This is my second grow, so I'm not too sure if my plant is doing well. The leaves are starting to turn yellow and also purple. I could use some input to see if I'm on the right track and if I need to change anything. Also today I found a leaf that had some red spotting...any deficiencies ?

This is a purple strain. What did you run before? Very normal at this time.
