Small Yellowing Spots Starting On Leaves?

[Creep420]

Hello everybody.
I am having an issue with my girls; I am seeing small yellowish spots on the leaves beginning to grow on a couple of them.
They aren’t rustic from what I can see, but concerning nonetheless.

First time grower here so I am trying to learn everything I can.

-I have them in a mix of Fox Farm Ocean, Pro Mix and perlite mixed for drainage
-74 degrees F
-Good drainage
-Ph is 6.5
-200 Watt HPS on 12/12 started to flower last week.
-2’ above canopy
-Water once every 4 days generally
-Intake and exhaust fan keeps fresh air in and out. Along with an ocelating fan keeping the air moving

3 months old, haven’t used any nutes as the soil was kind of hot in the beginning.
Hoping to god this isn’t a fungus, I’ve been stressing over it so badly
Any advice will help! Thank you in advance.

Doesnt look like a fungus. how many leaves is it on? Can we see a pic of the whole plant?

At this age even in that soil, it could probably do with some added nutrition.

Looks like you may have splashed some water or nutrient solution on them with the lights on. Looks fine otherwise. You might want to hit them with some nutrients soon.

Understood and thank you both.
I have taken a few of photos. Maybe it could have been water hitting some leaves and getting burnt from the light then. I have noticed that on some leaves there is slight discoloration, almost a blotched pattern. You can kind of see it in The first photo.
Luckily those yellow spots are only on a couple leaves on 2 plants.
The bottom yellow leaves were from nute burn at an early stage and I let them be to take in light.

What would you recommend as for added nutrients for plants that just started to flower?

Here is another example of the discoloration of what I am also seeing on a few leaves

Upon closer inspection the same kind of blotches are found on multiple leaves on different plants.
Possibly need nutrients added finally?
