So a little opening details. This is my first grow. I am 30 days into flower currently. 5 gallon pots 250w super hps in 3x3x6ft tent. The air flow outtake goes outside, passive intake on bottom. Sadly no oscillating fans, but I have 2 stagnant fans directing airflow to carbon filter in tent and not directly on top of plants to prevent wind burn or whatever. I am using FFOF soil with Fox Farm Trio for nutrients. I give them each a gallon of 6.2-6.6 pH distilled/purified water per feed every 4 days or so. I live in a humid area so I am using a large dehumidifier in the surrounding room to keep humidity below 50%.
.
Onto the issue. So after this last feed I have noticed these little patches showing up on the leaves. I can't seem to find pictures that look quite like it anywhere. Or maybe I just don't know what to look for. The spots are somewhat persistent, which is what has me a little worried. A part of me thought maybe it was white powdery mildew. Although the spots have a white tint to them, they do not appear powdery in any way. Although maybe this is just the very first signs of powdery mildew?? I tried looking up other forms of mildew and honeydew and all sorts of things. And haven't found anything quite like this. The spots rub off if you rub your finger over them. But they keep appearing over the plant.
.
I will add though that besides this the plants overall appear pretty healthy. A slight tinge of yellow at the tips of some leaves tells me I might have a very slight nutrient deficiency. So beyond that and these spots, they appear to be doing fine. Also I took these pictures under the hps light so the coloring may appear slightly off. They are in flower so I didn't wanna expose them to light during their dark time just to take pictures with grow light off.
.
If anyone has an idea of what this could be, or if it is something I should be worried about please share.
