Your first mistake was using Miracle Grow as soil. The soil performs terrible with the time released capsules of nutrients in them which can cause cannabis to suffer toxicities and/or deficiencies. Cannabis need certain amounts and certain kinds of nutrients throughout it's entire life-cycle. Using that soil does not really allow this. Anyways, I would start introducing some cal-mag into your feedings and the problem "should" correct itself. Please note that damaged leaves won't recover.

I don't know exactly what you're talking about with the lights but there's a reason people use good lights. It's not just a trend and if you actually did your research you'd know that.
I don't think you need to add more nutes. A pH of 6 is too low for the plant to get the calcium it needs. Raise your pH to 6.8 and see how it does.

Hi there having a similar problem hoping to find some help thanks, HI there newish grower here, on my second batch, all my babys look good except for this one, noticed small orange dots on it about 3 days ago, now as you can see in the pics its gotten much worse, I believe its a cal-mag deficiency but not sure. Im a bit confused as its the only one of 4 plants that have it. I use coco with some perlite, and Advanced nutrients base nutrients, the PH perfect for coco. The plants are loving it other then that one plant of course. Hoping its a easy fix and just for whatever reason this plant had not got enough cal-mag, i was told not to add anymore to whats already in the base nutrients so i havent
