General concerns about the plant health and expectations from her.

A little nute burn won't affect your yield, but you are starting to lose leaves. Those leaves are what process nutrients to feed your flowers so losing a lot of leaves will lower your yield and quality. Your buds do have the ability to get much larger if the issues you have are corrected. The leaf coloring is not normal at this stage. And yes fortunately you can correct this and get her turned around. I saw that you just gave her a flush. This is definitely what she needed because I think your issues are from excess salts built up in your soil from all of the nutrients. After letting her dry out a lot then you want to feed only every third watering. So feed, water, water, repeat. This will help prevent nutrient and salts from building up around your roots. It also looks like your flowering stretch is about over so you want to back off the nitrogen as much as possible. The plant doesn't have much need for the grow big from here on. I would check out the fox farm feeding schedule and feed half the recommended dose on their chart every third watering. Also make sure you adjust the pH to around 6.5 to avoid other lockout problems. This should clear up your issues. Good luck finishing up your grow!
