Mystery spots- Please Help! Pics

Hey All,

I have these lime green/light brown spots on the lower 3 sets of fan leaves of one of my plants. I have had pH issues in the past and this looks different.

I have 13 6-week old plants growing from bagseed in Fertilome soil. I started fertilizing at 4 weeks with a 1/4 strength dose of Age Old Grow 12-6-6. Then a week later fed again with 1/2 strength Age Old Grow + Cal-Mag. Watering when top 1-2 inches of soil are dry, usually every 2-3 days (I live in a dry climate). 24 hour photoperiod under CFL's 3 inches above plants.

I have a jar of Ona Block (odor neutralizing agent) that was sitting next to that plant, so it could be an Ozone problem, but since I've moved the block away almost a week ago, the leaves have been doing slightly worse and worse every day.

I have been having issues with fungus gnats flying around for the last 6 weeks, and from what I've been reading, they might be attacking the roots of this plant. But then why just her? Or is she just more sensitive? Does it look like a pH/deficiency issue after all? Maybe pH fluctuations between feedings? Poor ventilation?

Please please please help me figure this out.

I don't want to lose her. Thank you a hundred times for whatever help you may offer.

Ok, I'm pretty sure that these are ozone spots.

ozone spots are a possible problem, but they are rare, do you have co2 right by your plant? My guess is either early onset nute burn or overwatering, I'd cut back just a bit on both and see if that makes a difference.

Bugs, pests, possibillity

I had an Ona Block right next to the plant and it has been moved now. All the other plants are fine, except for this one. Which leads me to believe that it's the ozone. I don't see any other bugs or eggs except for the fungus gnats flying around. I already have the sticky traps up, but those things catch like 8 flies.

I've heard that hydrogen peroxide is effective, but also kills the good microbes along with the bad making the plant more susceptible to future problems. I've sure you have to weigh your options and do what's best for the plant. Would you suggest watering with an H2O2 solution?

I don't think gnats can produce spots like that, can they? I'm leaning toward the ozone spots.

looks like spider mites

Spidermites bro.

TrynaGroSumShyt that is what i thought too!!!

I've had spider mites on leafy plants before in other houses. There are no bugs, no wispy webs, no eggs, nothing to suggest bugs. Besides, spider mites would most certainly go for the other 5 plants sharing that closet. I've been scratching my head for days trying to figure it out.

agreed normally spider mites leave signs of their excistance. Your odor blocker could be the problem, whenever something like this happens just keep making minor changes until something fixes it, don't try and reinvent the wheel, anyways good luck

The little holes are the deciding factor. Something was hungary
