It is a little early to be positive on my part yet, but this is exactly my issue. The little brown dots moving up.

FIRST your plant will be okay and make good meds.

Second, I am beginning to come to the belief this is a "Cal/Mag" problem as that is what I am adding to my water and the leaves seem to be doing more of a general yellowing - as they should -as they reach maturity.

This has been a 3 week process. Now, along with that, my water PH is like 6, I use RO. Adding the CalMag really lowers the PH and I have to use PH up (sodium bicarbonate) to control that. With your pH, you probably will not need to buffer it. Currently I am adding 1 teaspoon of Cal/Mag (derived from molasses) in 5 gallons of water.

I do not get runoff either. I only transplant one time in the flower room and it has no effect or even worsens the problem (FFOF).

So slowly you might consider such a treatment. The response has been slow as I am hesitant to use many buffers (salts). Looking for the minimum to resolve the issue and so far - over time - it seems to be helping more than anything else I have tried.

Link to other recent thread, same issue....seems more common.
