leaf symptoms

It looks like the leaves were wet when lights were on and the water magnified the light and light bleached little spots everywhere. You are only one that knows if that happens. Good luck and happy growing. Hopefully I helped 🌱🌱🌱

Check your plants thoroughly, top of leaves, bottom of leaves, and stem. I don't think that's pest problems, but I could be wrong. I notice a few of my plants did that on a leaf or 2 but then it just went away and never came back. If your worried about bugs, you can use Azamax or azapro in the veg stage, IF your ok with pesticides. I have stopped using pesticides and increased air circulation because bugs hate to much wind movement, and start foliar feeding Armor Si when will make your plants strong and bugs hate the taste of what it's on. If you use Armor Si dilution is important. I use 1/4 the recommended dose a d If I spray to heavily and it sits to long it will burn your leaves, not from light but from the nutrient itself. Once you dial in the use of it, you'll see a big difference in plant health, stem size, and bugs just won't eat them anymore. That's just my opinion and practice from people experience.
