Do a good dry back. Cal mag if you havent. Also lower the light if you can (prob just a few days) Just to let her adjust.
Whats the ph level at on run off and the water you use?

I've given her cal mag a few times.
The light is at lowest setting, 40% .

Came across a few cool sites that help you calculate and adjust lights .

https://growlightmeter.com/calculator/. --- Calculates daily light integral (DLI)
https://www.cocoforcannabis.com/grow-light-guide ----- Light info / details

*** I left a piece of info out. Two days before she took a " dive " , I broke her main stem. Near the top of the stem, only 3 nodes were taken ( had 9 total nodes ) . So I went ahead and made a clean cut to " Top " the plant . Been 5 days, not healed completely yet

I haven't seen topping stress this hard . But I did begin LST at week 4 prior to topping .

Perhaps a perfect storm of all types of stress?

I've heard that the leafs shrink and bend when too much there is too much light. So perhaps that is the main issue. Maybe I can get a controller and get the light down to 20% or less.

Your output setting it perfect.
Just raise your light, its the beginnings of just a mag def.
Id use salts and raise that light to 26in above canopy.

Thanks. How often and how much would you suggest?

2-5 grams a gallon
And at your normal feed rate.
The discoloration may get a little worse before its stops completely.
Affected leaves may gain some green pigment back. But the bulk of the changes from the def will stay. Just monitor all new growth to ensure either,
Your light is dialed, may still need to raise some more since your light has presets for output.
Or that you have the salts dialed in,
