I would flush it, let it dry, then go straight with a regular watering with normal nutrients and some extra call & mag, i would take those dead leafs, because they will never get back in shape, and i would keep an eye to see improvement, make sure that it is not a ph issue locking out minerals.

Yes I did just that. I'm thinking magnesium deficiency. I use straight rain water. I don't even check pH. Next grow I will and compare the 2. Just strange to happen so fast in a shirt period of time.

You just told whats wrong mate, Rain water, is basically RO water, low PPM, almost none minerals.
The minerals come from minerals sources, when it rains on mountains we take the water from the fountain and it has the minerals on it after going through the earth, but clouds are similar to RO filters eheh, so its pure water, is a great base, i personally use similar water but i plant aeroponics.
Make sure that you add always CAL&MAG, don't add big quantities, not needed, just enough.
I start to add cal&mag on my plants after they reach 10cm lets say, just example, from there i only stop at week 6 of flowering.

another thing, sometimes you need to use special fertilizers for soft water (like i do), depending on your fertilizers brand you need to check that with your supplier. But if you plan to keep running soft water such as rainwater, you need to check that, otherwise, you loosing big on the yields!

And if you plan to use tap water, you need to find out if your local water is soft or hard, depending on that you will know what to add to the water, lucky me that my water is soft, its easier for me to play around with the nutrients

It also looks like septoria. It effects tomato plants as well. Unfortunately it effects cannabis as well. It's a fungus, and bitch to get rid of . just a.thought.

Plant is looking way better today. Watered with Cal Mag and also did a foliar feed as well. Picked off all those brown leaves. From what I researched it looks like a magnesium defiency.

I agree on the cal mag, but why would you flush?
edit:I just noticed you mention ph, but in soil, watered with rain water I doubt that would be the issue
