GCS Purple Haze w/ Short Veg

Really happy with this one so far. 💜 Minimal issues and it’s soaking up the nutes. I increased the bloom nutrients and now I am watering every other day, about 3L per watering, and nutes every other watering. All of my plants have developed some weird spots on the leaves. I think it’s a fungus but I am not totally sure. Initially I was thinking calcium/mag deficiency but nothing seemed to fix it and from what I’ve red, round spots are more likely mold than a deficiency. It doesn’t seem to be stunting growth too much but I’m worried it’ll get worse further into flowering.
