Look a bit like the leaves are just very mature and are dying off, theres plenty of foliage there to cope...imo:leaf:

Can this be reversed? I flushed her with about 4 gallons of ph water

No it can't be reversed. Flushing large amounts of water through the pots can cause other problems. I don't know what you're growing in but if it's soil you don't have to feed every watering. More is not necessarily better.

Looks like a CalMag Deficiency to me. what ppm have you been giving?

There is no such thing as a calmag deficiency. There is calcium deficiency and magnesium deficiency. Calmag is not an element. There is no need to even feed calmag if your nutrients have enough calcium and magnesium. If you're growing in any decent soil there is already calcium. Water with tap water and even more calcium and magnesium.

And they have been feeding calmag along with GH so they should have more than enough calcium. In fact too much calcium can be detrimental. Calmag is not a requirement. It used to be used mostly by hydro growers and people using RO water. Now it's like some kind of buzz word. I've never used calmag in my life.

That plant has been fed more than enough of everything. Overfeeding can cause nutrient deficiencies.

Dude, I really do appreciate all the help you give to the community but a lot of your comments come across as condescending/douchy. Just thought i'd let you know how you come across in case you don't mean too

Post of the year. Bravo!

The plants are burnt to a crisp from overfeeding. If you think the solution is more calmag then you're wrong. Too much calcium can cause nutrient antagonism which is why so many have screwed up plants. Too much calcium can lockout P, K Mg, Fe and other elements. In most cases nutrient issues are caused by overfeeding.

What criteria are you using to say that plant has a calmag deficiency? Is it just deficient for calcium, magnesium or both?

You have a right to think I'm a condescending douche. I have the right to not give a damn what you think and I don't.
