I would definetly do the Transplant

As far as the Problem I would try a good Flush

There is a product called Insta Green I would give that a shot very high in Nitro and provides a quick turn around

If their were bugs you would see them do you If so how about some neem oil

I would try the transplant the feet are probably not happy and the Insta Geen should turn things around for you maybe even throw a TEA into the equation

Good Luck
legalEYESit Reviewed by legalEYESit on . Problem with 2 Bubba Kush's Not sure if I have a spider mite problem or if it is just time to change to a flowering stage fertilizer. Some older leaf growth is dying and some younger growth is yellowing. I am giving them "Grow More" 20/20/20 and they are about two months old, over 2 feet wide and tall. They are outside plants, and water and soil are good to go. I feed all my plants, except my Super Silver Haze's, the same fertilizer ratio and the rest are all doing great. This is why I assumed it was a pest Rating: 5
