Flowering Issues

Alright this is my situation.
I posted about this before where my plant seemed to be angry about a nute burn or ph related issue so i flushed the plant with about 4 gallons of water (which was an incedible task to do being that my plant decided she wanted to take a nap half way through and started falling over which was an intense two hand task)
Anyways, the problem isnt seeming to get any better, i have only fed it water since this occurence and the leaves are starting to yellow even more and die. What should i do? I know this is really not good thing to happen at this stage?
I really need some help before it really affects my yeild.

to me it looks like either a Manganese or Magnesium disorder

quick dude, you need to harvest now or else that bud will start to rot!

any one else?

You think its that bad i need to cut her down?

oh no, lol my fault, I was talking out my ass. I don't really know what it is thats wrong with that plant. disregard my last comment.

Oh, thank you, that clears things up.
I knew you had your head up your ass.

I've seen this before. My brother foliar fed twice in one week and the plant spotted like that. It's just a chem burn I think. I just pulled the really sick leaves and left the slightly damaged. Your plant won't perform as perfect as a healthy one, but no worries she live.

Thats good to know. Do you think i should feed it at a normal or low dosage of nutes at this point? or just water?

Make sure the ph is in range 5.5 to 5.8 and use either a weak solution or just plain water. If you have an RO system use that water. Also if you're using an RO system it buffers the water to stay neutral so check the ph as often as you can. If the acidity builds up in the soil or the hydro setup you need to bring it down. A lot of people just you a ph up or down but I recommend adding plain water that is ph corrected until the desired ph is met. I hope this helps. Sorry for the delay in my response.

it looks fairly close o being ready to harvest, how many weeks into flowering r u in?
