1. stop smoking american spirit rollies
2. switch to cloves... they will kill you faster..
3. time to get down to business
4. if you are worried, change all the water.. go get distilled water from store and flush system..
5. are the roots mushy and brown.. or just brown..
6.. you will know if your roots are rotten. roots should be strong and should not pull apart like a gelatinous goo
7. if roots are dead, cut them off.. that dead shit will consume all the oxygen in your water.
8. don't worry about the brown spots on your leaves.. just flush with distilled water and clean off dead matter.

9. take better pics and report back.

good luck and I feel for you..

did you take clones yet?
