WTF?

[BillBates]

What's this black stuff?

[Chefbjy]

Check for bugs?

[BillBates]

Well, they're outdoors, so there's definitely bugs but this is different.

[Chefbjy]

Keep an eye out...there's some wierd bugs out there that aren't necessarily a problem unless it becomes an infestation. Wierd though doesn't seem to be munched on but I hope it's just a minor occurrence and everything turns out okay.

10-4 ......

what da fuck indeed, never seen anything like that before

Hey Bill, when did you first notice that sh- t ? That don't look good.
If it ain't bugs, my guess is some sort of mold or fungus , is your humidity ok ?

[KingKush]

It reminds me of slime mold, which happens on the golf course tees and fairways sometimes in summertime. Looks like fungus growing, and it is, but it actually is harmless, just physical. A nusiance but not a pest.

Or it it could be abiotic (physical damage) like some water droplets or moisture that when the sun hits, acts like a magnifying glass.

Seems like a pigment change inside the plant's cells, could just be a particular strain starting to hue purple.

Let us know what else you can observe, if it spreads, or which plants are affected. Hope it is one of the harmless options.

I know what it is lol. Had it happen to me last grow when i fucked up and gave my flower girls the gh trio at 10ml a bottle cuz i followed the bottle. its super nute burn!

[BillBates]

I don't know where the nutes came from. I haven't fed them anything but plain water so far.

[Happygrower456]

Hrm weird then thats how mine did it.. learned a good lesson that day. the leaves looked like that but grew out fine but you could defintly see on the leaf when they took in the nutes!

[BillBates]

It's on 3 new growths & only on Northern Lights. Blueberry, Super Lemon Haze & Cindarella 99 have nothing like it on them. These are all outdoors within 10 feet of each other & have been weathering lots of rain (true downpours) for about 2 weeks now. I originally thought mold but it doesn't rub off. It doesn't seem to be causing a problem yet. Until I'm advised to remove or treat, I'm leaving it alone.

[D.A.A.S.69]

Yeah, thats weather, rain related, i wouldn't worry with it, unless it gets much worse,
Maybe, the weather, will change for you,lol. And you will get a good breeze blowing on them from the wind, that will help.
But you are staying on top of it, and you will be fine. I think. Good Luck with your plants.

Thanks Daas. That kind of encouragement goes a long way.
