Spider mites? Thrips? Not sure what I’m facing here.

[Rickysticky808]

Hi all,

Got some problems in my garden and having a tough time identifying exactly what’s happening.

I’ve had spider mites before so that’s my first guess and what I’ve been spraying for but I’m seeing really odd leaf formations (“burned”/bitten edges?) and even some signs of something biting the leaves (distinct holes)

Can’t find anything except little black dots but they never seem to move unlike Spider mites I’ve battled in the past.

Looked up and found thrips and thrip poop but haven’t really seen any or none that move.

Its (something) is attacking one plant pretty bad and seems to be spreading nearby, plants further away seem better.

Any and all help is much appreciated!

(Just flipped from Veg, soil grow, under HPS and some mixed in LED)

Looks like nute burn, but if you actually seen a pest DE earth there asses. Check ph.

Can you get close ups of those little black specs on the ubderside of that one leaf?

Kind of hard to tell what's going on other than a bit of nute burn. HPS is almost as bad as blurple lights for taking pics :)

The leaf damage does appear to be a pest of some kind but it's hard to tell without some close ups of any offending insects.

Of course we assume everything else about the grow is spot on in terms of nutes and environment.

Thanks for stopping by, much appreciated.

I trashed the leaf and sprayed this morning so nothing in sight at the moment.

Just tried to zoom in on the picture but not sure that helps much.

Thanks for stopping by, yea not very good pics on my part!

Deff a little hot for the ladies too unfortunately, no matter what I try can’t seem to get em out of low 80’s.

I find that keeping the window in my grow room slightly cracked and my humidified running helps to regulate my temp in there fairly well. Hope that helps!

Hi there! That what my friend said, he's a pretty experienced grower


-Use Trifecta Crop Control in combination with Beauvaria (a beneficial fungus)
- Hang blue sticky traps
-Place a colony of predatory insects in your garden (green lacewings, predatory mites, minute pirate bugs and specific parasitic wasps)
-When there are only a few thrips on cannabis, the damaged areas can simply be cut off.

So update I got the heat down to about 78 so that’s one improvement.

After spray no sign of anything until today. Found this little black bugger.

Seems longer than any spider mite I’ve ever seen.

Couldn’t see it moving at all and tried to snap best pics I could. Paper clip head in some for size.

Is this a thrip?


Also found one light green kind of sac but then lost it before I could snap a photo.

Hey guys trying one more time to get a better shot.

still lots of black stuff coming up on leaves but no sign of movement.

Just these kind of long brownish looking things that also never seem to move.

I keep hitting em with alcohol/soap combo and that seems to keep things dead but not getting rid of them.

Deff thinking it’s thrips at this point but any thoughts are greatly appreciated!

 

[Rickysticky808]

Last shot is the black specs that are left on the leaf.

I’ve had spider mites before but this doesn’t seem like them really.

Do you see any flying bugs?
Possibly treating soil for gnats may help?
I like mosquito bits myself.

No not anymore. Deff have gotten em from time to time but nothing crazy.

A good “dry out” of the growing medium before next watering plus a spray of some soap should knock down your Nat problem.

I’ve been spraying with a tea tree/ peppermint oil / alcohol spray and that’s been killing most things. Really nice smell too. Recipes in the link below

Deff seems like something munching on my leaves still tho and I keep finding these black spots and weird little “brownish” bugs

I stay away from soaps. I really hate the idea of spraying my plants.
The dry out won't eliminate gnats.
The mosquito bits work fast enough to notice. They are a bacteria that targets the gnat, not a chemical. Safe to everything but bugs.
If your recipe spray is as good as it smells then why do you still have pest?
The little brown thing that does not move looks like gnat larvae.
Just saying.

*update*

So it seems I had a lot going on that could be trouble so trying to narrow down one by one made some progress, hopefully it will show.

My PH was low at about 5-5.5, spent a bit adjusting PH Up and should be in better shape going forward.

Deff had nutes burn going on as well. After double checking bottle I messed up the dosage. (My old eyes read tablespoon instead of teaspoon)

So flushing them now with proper PH should help some.


The Temp is now in the high 70’s instead of mid to low 80’s (should also help going forward.)


As to the pests I simply can’t find anything living with my 40x scope.

Taking a shot in the dark but I could be seeing “casts” and/or dead bugs or their shells b/c I have been spraying for weeks.

Still seems like an awful lot of black shit but no sign of anything living when I do the printer paper test daily and not the tell tale signs of mites that I’ve experienced before.


I saw one flyer but couldn’t catch him so hoping that’s a fungus gnat who will shortly meet his maker also.


Will keep updating but fingers crossed I can salvage something from these ladies. 4 weeks into flower and they seem behind thanks to my dropping several balls on this grow
