Soil Type = Vermont Compost Company - Fort Light compost based potting soil (linked)

Always adjusted my tap (not RO) water's PH for watering.

As for nutrients, I was told with this soil and the short length of time for Autoflowering cannabis that I really didn't need the addition of nutrients.

That being said, since the issue with this one plant and the leaves I did go by a small container of cal-mag to try and help it as outlined in an above post.

After the first watering of 1/2 recommended dose per gallon from the container and a week going by with the cal-mag addition for that plant, I continued to see more leaves at the top (even up to the small sugars on flowers) developing the spots and becoming what i would consider brittle and dry.

When it came time for the next watering, I gave the full recommended dose of cal-mag and seeing the same issue, I came online for some help.

Please let me know polishpollack if there is any other information needed.

Thanks again.

7 to 10 gallons maybe you wouldn't need to feed but in 5 gallons, eh? Kind of borderline (depending on the soil) I think your pH is too low your locking out, as I mentioned earlier, maintain a steady 6.5 for best results
