Plants Yellowing Brown Dots Help!

My setup:

4x4 grow tent
600 watt mh
plants in 1 gallon buckets
Soil is ocean forest
Age: 4 weeks 1 day
Average room temps during day: 75-81 degrees
Ph of water adjusted to 6.5

About a week ago I noticed a couple plants developing yellow around the edges of a couple plants as well as brownish dots appearing along the edges as well. I was advised that it was a calmag deficiency so I immediately foliage sprayed with espom salts followed up with cal mag + a day or so later. I have seen no improvement at all sense I sprayed 4 days ago in fact they are continuing to get much worse. Im running ocean forest and have not watered in any nutrients as the soil is pretty hot. I did overwater last time I watered which was about 5 days ago and the soil is still a bit wet. I did poke holes in it to aerate it a bit. Checked my runoff which was fine and no signs of pests. We're Transplanted 10 days ago. Any help would be greatly appreciated

The problem is your drainage. You should repot and add about 25% perlite. If you can put them into larger pots now is the time. They are too wet.

That does look like some over watering happening probably due to as cindysid said your drainage is not quite where it should be especially if the soil is moist 5 days after watering. You're plant is getting oxygen starved. If poking holes does not help as you said I also would re-pot into at least a 1/3 perilite to soil ratio. (or 1/4 either works to each their own )

Jubilant is right. A bit more perlite might be a good idea, and let them dry out until the pot is light.

That pot should feel dry dry dry almost two knuckles deep (for me which is about an inch and a half) before more water is added, remember your roots need to breeeaathee
