Nutrient burn or potassium deficiency?

Yes just turned the lights off while watering the plants, I don't have grow light glasses. Took a picture shortly after

Ok so I'd say two months in, whenever I water the plants, the soil doesn't retain much water. It runs off very easily. But the soil would stay moist for 2-3 days nonetheless.

You probably have a lock out.

This was the soil https://www.canadiantire.ca/en/pdp/golfgreen-potting-soil-25-l-0591403p.html#srp

So if my ph is 6.5, I need to bring it down to correct the lockout, is that correct?

Never interrupt the light. It will confuse the plants. Some cases they will herm.

PH in soil ? Yes. But I would make a flush actually

I once flowered 4 plants with no nutrients since before the switch. They produced way more than I imagined which leads me to believe the amount of nutrients the plant stores during veg is essential for the stretch. The plants grew tall but the buds were small and two of them hermied and that’s how I created my first cross/feminized seeds. I’ve grown around 40 of those seeds and only had 3 true hermies. A couple of banana throwers and 35 solid females.

I have plants in normal soil - week 2 bloom. Only fed them once with bloom nutrients. No veg nutes at all

You need to flush the plants. The pH is very important, but getting all the salts out of the soil if they did build up, is also important. This is a tutorial on flushing a sick plant: https://www.growweedeasy.com/flushing-sick-cannabis
