a few things could of happened you have root rot which will mess up your plant. the ph you feed it at should be 6.5. and add microbes next time. Microbes would of helped the root rot if that is it actual problem too. so microbes help alot. When you think things in your pot are to hot/salty flush each pot with about ten gallons through it then just renute with half strength. You can do that now I guess and then leave it alone and let the pot dry out a little. Not going to reread all the posts but do you feel that you had overwatered it. That will get things messed up. You got decent nutes got to think balanced nutrition when you do this. I did go back and check and I still dont like your 5/50/17 nutes thought that was you. Yoiu got a ppm meter? what ppm where you feeding it at. nitrogen is the grow, phospurous is the health and potasium is the energy elements. epsom salt/mag would of helped the plant long ago. Answer me this. Magnesium is the center molecule of blank production. Do you know what it is.?/
Just ride it out and get it next time.Still looks like killer buds.
