Possible plant issue

I watered yesterday with miracle grow 11-3-8 . I have been using this and doing well with organic soil. Today I noticed these spots. I don’t have a good ph meter. With 2 junk ones it’s read almost 8. They are in week 7 of vege and I topped 1 week ago. It’s only on 2 plants and they were my slower plants. I also pictured all my plants.

Soil? Dirt soil or peat mix soil?

Soil miracle grow organics

Okay your medium is already fortified. You only need to water. I’ve used this soil last year. A little short on perlite but decent otherwise. Then you fed more. Suggest not doing anything but watering until they show a deficiency.

Thank u

And make sure to ph at 6.5-7. Very important in MG soil. Try to get your hands on a ph meter ASAP.

You are talking about soil pH meters I'm guessing? I wouldn’t even bother if it's one of those 3-in-1 moisture, pH, etc meters. You want to use a pH meter that is calibrated and test the water you are giving to them. Use pH up or down to adjust it to 6.5 and then water when dry.
