Spinosad during flower

[Sir Digby]

I'm 4 weeks into flower and I've been noticing some holes appearing on fan leaves throughout my grow tent. It started mainly with one plant and I thought it was a deficiency but now it's showing up on basically all of them along with some white debris on lower leaves. Not sure if that could be thrip eggs or what but I've looked at the little white specks under my loupe and macro lenses and they don't seem to be living or moving.

Otherwise I haven't been able to find any other pests themselves on top or bottoms of leaves, but I want to get whatever it is taken care of and thinking of giving them a foliar spray of Monterey spinosad. Anyone every have good or bad experience doing this half way through flower?

 

[AngryBird]

Does it look like spider webs?

 

[Sir Digby]

No, I haven't seen any webs yet. just the holes in the leaves and the little white specks on the bottom leaves. Here are some pics

white specks on the bottom leaves, which is a little hard to see

Do you have any neem oil or food graded diatomaceous earth?

I do have some neem concentrate. I don't have any diatomaceous earth though

 

[AngryBird]

Either is fine
I am not familiar with neem as of dilute etc.
But you need to spray the lady.

 

[Sir Digby]

It has the dilution rates on the bottle so that shouldn't be an issue. Should I use it to spray everything including buds or what? I picked this stuff up quite awhile ago but have never actually used it

 

[AngryBird]

I would try to avoid the buds....

 

[Sir Digby]

Sounds good, I'll give that a shot.

 

[Sir Digby]

If I pick up some diatomaceous earth to avoid issues with the neem and buds do I dust all of the fan leaves with it or the top of the medium or what?

 

[AngryBird]

Yes, and after harvest, you will do budwashing so diatomaceous earth will be rinsed off.
Neem is liquid and I'm afraid it might cause rot.

 

[Sir Digby]

Cool, I might try to pick some of that up then. So are you not a fan of spinosad? I've read a lot of people liking to use it in flower

 

[AngryBird]

I have never seen that. So I can't speak for or against it.
After some checking, yes you can use it... Not on buds though.

 

[Sir Digby]

So I'm pretty sure I just saw a tiny little adult thrip on top of one of the leaves. It was tiny like a flea and then jumped out of sight as soon as I went in to touch the leaf.

Use it!

 

[Sir Digby]

The girls got a full spray down last night along with the tent, hopefully that will slow them down

 

[AngryBird]

Better safe than sorry.
Just be careful with buds and moist. Make sure humidity is not going high.

 

[Sir Digby]

I went ahead and let them dry outside of the tent last night. The instructions say to avoid direct sunlight or heavy winds, I figured the lights and fan in the tent would be equally unhelpful. Plus I wanted to spray down the tent. Humidity only got to a high of 57% over the past 24 hours so hopefully no moisture issues.

So far today they're looking pretty good. I haven't seen any more thrips, but then again I've only seen one the entire time I've been searching. Hopefully they will all be on the road to recovery now.

 

[AngryBird]

Just in case, do the spray routine after
A few days...

 

[Sir Digby]

I think I'm going to hit them again over this weekend.
