Cut now? Cut later? Rescue mission?

Basic info:
4th week of flowering( or maybe a bit more)
Blue cheese
Feeding basic nutes and molasses(up to now)

Problem:
two weeks ago I noticed some weird spots on only one of the top leaves, they were brown and very very small.
Decided to wait and see what happens. Turns out, after a week the whole leaf is covered in these very small rust spots and some of the lower leaves are starting to get the same ones.
Thats when I figured out that it could be Mag or Cal def. But still, I waited to see what would happen over time, see if its gonna fix itself(cause plants are that awesome sometimes).
It got worse, I knew that molasses contained a good amount of Cal, so when it was time for watering, I decided to flush with molasses to fix the cal problem. But then.......
DUN DUN DUN. One day later, the whole plant looks like shit, not only the rust spots are all over, but the leaves were beginning to get really light green, and yellow at some places.
So i search a bit, see that it is Cal and Mag def, i run a ph test, and the results blow me away, the meter was at 4.7.
"instantly teleport" to the market.
Proceed to buy dolomite lime.
Then i put the required quantity of dolomite lime in the first two inches of the soil. (3 oz approx.)

The hard decision:
I had just flushed two days ago with molasses, seeing the very fucking fast progression of the yellowing/rusting spots. I just decide to water anyways.
The progression did slow a bit, but its still only getting worse.

THE BIG QUESTIONS:
The soil will not be dry enough to water till a fucking week and a half or two.(the plant will be fucking dead by that time IMO)

-So do i wait? and water with a bit more dolomite lime?

-Or i cut now, dry and have good weed to smoke? Or its gonna be bad?

-Or i cut now , dry and make hash?

WHICH OPTION IS THE BEST? CAN I SAVE MY BABY? IF I CANT, WILL IT BE GOOD SMOKE OR FUCK DAT LETS JUST MAKE HASH?

Im very frustrated against myself for not being more cautious with my babe, now i guess im paying the price......

I just hope you guys will answer, thanks for the time, really guys, thanks..

Strange, I have never seen leaves shaped like yours. Extremely long and broad. Have you checked for bug activity under the leaves? You also may have more than one problem working. Since it appears to be affecting the plant from the lower leaves up you might possibly be having root aphid probs mixed with something else.

no bugs... 99% sure about it. Checked multiple times.

IMO. it's the molasses. you don't need to add it to every watering. ESP if you are flushing. only flush with pure water; the point behind flushing is getting rid of all excess nutrients/elements and you won't do that adding molasses. I've notcied my PH goes bizerk if i add too much molasses or add it too often. Now i only add molasses during flowering MAYBE 2 times, but usually once.

Cal/MAg are only needed in small amounts. Molasses in one feed should be about all you need.

get some earthworm casting tea and top dress with a some earthworm castings... pluck off the dying leaves.

it needs nitrogen &/or magnesium

Cal/mag deficiency usually starts at the bottom of the plant. You should do a soil test to get a real answer, and they are on Amazon for around $20. Also, why does it take so long for your soil to dry? Sounds like you don't have any drainage at all which can be an issue also. Good luck

Sounds like what im going through first time soil and started having all the symptoms you are saying. I gave mine ro water every time its thirsty and seems to be slowly coming back!
