In week 3 of flower

Was this a sudden thing? What has changed since you started flowering?

Can you post a picture of the overall plant too?

It started before i switched to flowering already. Bottom leaves are mostly affected

Just added it. Little hard to see with the led lights

I don’t believe I’ve seen anything like this before. Are the little black spots bugs?

That looks like what I’ve had going on and
I hate to say it but could be spider mites.
Just doing some research and appears to be same as pics I found for those lil buggers. Hope I’m wrong. Maybe
@peachfuzz could take a look since he spotted my issue


If it is spider mites a good magnified picture of the underside of the leaf should show the little mites

Damn hope it’s not spidermites, will have a very close look when i get home. If it is spider mites, how do i treat that?

I used a 3% solution of hydrogen peroxide
Misted under sides and tops. Do at lights out or u could have light burn. Some people use neem oil instead. Lady bugs are a natural predator too. I had to remove the worst affected leaves and tossed /discarded. I also added 2 more fans to my set up to keep things moving. Hope it goes well. I hate the lil buggers.


I don’t see any red dots/mites on the bottom of any of the leaves. Zoomed in on top of the leaves does show little black spots. Looked with my jeweler loop and did see something tiny crawl, but not red. Almost see through!

Some sort of bug… start spraying asap… :wink:



Just googled it and found out it’s Thrips!


Glad u got them identified @420Gomez.
Now comes the treatment. Good luck.
Peace. :v:
