Hi, i don't know why but this NL Auto is having some strange spots that seem nutrient burn marks, but i'm under feeding for now my plants. I used a grow mix soil that is already fertilized for the first three weeks. Now it's the fourth week so i used a little bit of nutrient, half the quantity the bottle suggest. The other one seems to be really fine for now, even if i'm feeding It the same way. So dunno, really nutrient burn? Sort of parasite? photo below.
I have to say that two very hot days and then two very windy days have passed, then this spots appeared. Now is still windy a lot and there is nothing i can do, only moving plants inside but i don't think this is the problem
