HELP, problem has arisen over night

[T.rips]

this appears on the new growth and grows from the center of the leaf outwards

That's pretty wild, I've only seen pix. Is it likely it could be a Zn-? If so, should be fairly easy to fix up, assuming you're willing to use chemical salt fertilizers. If you're into organic, we need to find another route.

How far down the plant is it light green, or is it only the tops? Also, is there any chance the plant could be growing so fast it's outpaced its ability to translocate N?

~~EDIT~~
Fe-...? Happens frequently for me with my Camellia, is relatively easily fixed up.

it has pretty much taken up the whole plant, all of the new nodes, i was going to do a flush with epsom salt and half strength nutrients, and i though it was outgroing its capacity but i highly doubt it now, it has been going on for over a week now

have you fed them with your base nutes yet though? it seems like she's hungry and bearing with a lot of heat.

Immobile deficiency, meaning the plant isn't able to pull whatever it's missing from the lower leaves, chances are your pH is locking it out.

folar feed with a commercial cal/mg and try to get your rootzone pH right again,

Why Cal-Mag here?

I've lost my mind over "Broad mites" this last year so everything looks like broad mites to me...LOL, GL figuring it out, epson salt for sure, the curled fern-like top growth has me saying this. I'm prolly wrong,... broads mimic a deff exactly, hope your grow is spectacular...!
