Is this Leaf Septoria?

I dunno, maybe drips of nutrient solutions who knows, just a possibility.
besides. I already know the issue, its FOX FARMS

There's 0 possibility that nutrients have spilled on the leaves. In fact I hadn't even used nutrients for nearly a month before this issue appeared as I'd transplanted them into larger pots of FFOF & was letting them use up what was in the soil..

But it seems you're probably right that it's nutrients some how. At least the bit on top that is. I didn't try to wipe off the yellowish spots in the earlier pics yet so I'll try that when I get home & see. Maybe it's a nutrient issue && powdery mildew

I think whatever it is its mild enough for you to give it some time it may be nothing and resolve itself (as mentioned)

as for spraying for mildew... I spray a min. of biweekly even when my humidity is in range
if you can wipe the pm off the leaf your too late and should have sprayed before letting it advance to that point

and just because you cant see it doesn't mean its not there

You said "if you CAN wipe the pm off" did you mean CAN'T?

From what I've read aside from spraying as a preventative measure if it advances too much I'd want to cut off the effected leaves right?

I edited and corrected it before you copied it lol
yes I meant cant...look it says cant... read it again...what are you stoned or something...lol

lmao

I guess I should point out
azamax 1oz plus silica blast 1 oz per gallon (or substitute neem oil)

first time start with half dose to 3/4 dose first spray to make sure your plants aren't sensitive..

I have sprayed several strains without issue

I spray it a minimum of biweekly and when humidity is high more often (weekly)
I don't spray after the 5the week of 12/12
I spray more sparingly as flowers fatten and heavy (to run off) when in veg

if spraying frequently you may notice some mild burning and curling under on the very tips of the leaves.. similar to that burn that green cure can cause if over done

This part showed up very recently. Like after I started this thread. It's on top & the bit that wouldn't come kff when I tried wiping it off..

If I need to snip the effected leaves thats ok & honestly I have 2-3 too many pants in my tent as it is so I could even get rid of the entire plant. 4 of them are feom bag seeds & I had planned to only keep 1 once I determined their sex. I got lucky & was able to see 2 of them had female preflowers (love thise little hairs!)

Another thing I should mention is that I only noticed these issues on 1 plant. It happens to be closest to the heater however there is another plant just as close to the heater that doesnt show any of these issues so idk if that could be a contributing factor?

from the look of that pi alone I can not determine what it is

your lights are on and they are clearly affecting the picture

is it wide spread or only one leaf?

a picture of the entire plant would be good

im not as good with diagnosing bugs but, has something been munching on the leaf or is it just torn from burn

Just that 1 leaf & it seems torn from burn. Other than that & the yellowish spots on some of the lower leaves seen in the previous pics the plant looks perfect & I can't find a single bug in my entire tent.

I wouldn't be worried about 1 leaf

if you start to see it advance or spread to other plants then worry

I pluck lower leaves from healthy plants on the regular

Yeah good point. I'm now trying to find a good solution to my humidity & I'll juat keep spraying them every couple weeks just to be safe.
