Leaf Septoria?

I had this on my banana sativa grow a year or so back, it doesn't damage the buds only your leaves, it will lower your overall yield and depending on your strains stability it could self pollinate if stressed enough. Adding a thin layer of sand to the top of your soil or misting the soil with essential oils will help stop the spores that are in the soil doing more damage by preventing them getting airborne. Be sure to sterilise your tent and equipment down after your grow or it will be a problem next time. Consider a filter on the incoming air intake 👍 Goodluck whatever you decide

Look like spider mit infestation. I treat spider mites and aphids the same way. I use a anti-pest microbes calls Beauvaria bassiana. It makes the pest sick but live very shortly on the plant. Some strains, especially more indica are tolerant to pest. Land race Sativa are normally good against mold but not pest. Boutique strains may takes more skills. For expample, my Thai landrace grows are troubled by all kind of insects and mites but not mold.

You may have an aphid problem look under the leafs

P.S. Forgot to mention, the spotting is primarily on one of the 3 plants. Found it interesting the Caramelino is being affected, but most of the White Widow leaves are super healthy looking. Maybe a higher resilience between cultivar. Maybe I’m just catching it before it explodes. P.P.S. Also forgot to mention the plants are in their 7th week of flower, and 6th if you’re going off of the first pistils. Breeder says it’s a 8-9 week flower plant, so we’re getting close to the end.
