My WW is getting pale and tips are burning

My WW plant is about 1 month into flower now and a few days ago noticed her leaves were turning a pale yellow. This plant is a beast and so i thought possibly she needed some nitrogen. After a clean water feed i gave her 3/4 tsp big bloom, 1/2 tsp tiger bloom, and a teaspoon and a half of cal mag. Today i noticed her pale leaves were getting greener but she started a pretty bad burn on her tips!!! Im so worried about this plant since its so close to being done id love some insight as to what could have done this and how can i make her better? I will attach pictures. She is under a 300w amare COB 18in from it and is in fox farms ocean forest dirt. She vegged for 2 months and has flowered for 1 so im not sure if my soil is still hot or not.

Plants start taking energy from the leaves as they bud. It's normal.

She's on fire. You're going to need to do something about that soil now. Sorry, I'm not a nutrient guy though.

Oh, and FFOF is some really great stuff. Since your plant is so big, it would have needed to add nutrients at some point anyway. Was she showing signs of starving? Or was this love. You can still save her but it might be a bit of work with your setup.

Can you possibly post a few more pics from different angles? more helpful would be if you can post some pics from when it first started happening to now, or at least how the plant looked say 2 weeks ago? Do you know at what ppm's you've been feeding, and more importantly from the looks of it..what is the ph of water going in? What is your source of water?
