I think you can back off the cal mag at 8weeks on a auto.

Looks pretty normal to me, I would flush with water. And continue what your doing. I'm no master grower just my opinion.

Il give it a flush and see what happens, just to be clear a good flush would be to put say double the size of the pot for example 12 litre pot, put 24 litres of water through it once right?

Not to sure about autos but on my photos some yellowing towards the bottom is normal. As long as it's not affecting the middle or top only you should be fine.

I triple the pot size. I only ph the last bucket of water I run. And then I do my regular scheduled feeding at a half dose.

Your plant looks pretty good. A few leaves falling off from the bottom of the plant is not a problem. The above advice is sound. Flush and then reintroduce nutrients maybe at a lower strength

Are those leaves around the bottom touching the medium because that can cause them to have spots on them discolored as we'll
