Yo, that troubleshooting form is in my sig as well! :thumbsup:

I gotta say, to me this looks a simple case of over watering(you should be waiting about 3 days every watering, or when the top 3" of soil is DRY). it looks like you need to transplant to a bigger pot as well.

ALSO! Bigtops asked about nutes... I think thats part of the problem too. Probably need to start her on a 25% strength solution to get some of that color back.

good luck :thumbsup:
