Hi guys!

I carry on this problem for a long time without being able to solve it 100%.
Initially the plants were affected by thrips and spider mites and weakened, but after treatment with Borneo and Mavrik resumed normal growth in health.

As soon, however, come into bloom begin to behave in this way:





Even cloning a plant affected in the past, but now in health, when in bloom behaves the same way, without a new attack.
After 15/20days after 12/12 switch start to bloom normally.

Could be a virus/bacteria introduced by thrips? I really don't know!

Someone have any idea?

Thanks!
P

Can't really tell. The yellowing of your leaves within the bud show nutrient imbalance. Or over fertilizing. Cannot tell. Thrips are hard to kill.

Did you wipe down/clean the area where plants are located? Needs to be clean! Otherwise you''ll have a repeat of pest invasion.

Hi aridbud!

Sure, we clean everything before start and then!
The same thing is happening to a friend, on the same clones but also on different clones. Certainly in common we had an infestation of thrips.

Also this summer, in outdoor, some plants start to flower with great difficulty and then recover and bloom normally.
It seems that plants can fight this problem with flowering in autonomy...

Have you scoped for broad mites? I had some similar symptoms on plants that were populated by a light infestation. Heavier infestation you would have seen symptoms in veg. Took me a while before realizing what I was dealing with.

Good luck.

I agree, at first glance i thought broad(russet) mites. Get yourself a decent microscope and look for little larvae looking white worms. Be patient when looking though, they can be tough to spot.

Hi guys! Thanks for the answers!

I have done treatments after saw this... not before.

I know well mites but i have never seen tha plants behave in this way. For this reason it seems strange!

Surely thrips comes back , sometimes i find someone also after several treatments!
After this run I will clean all growbox and treat mother plants/clones with different products... I think it can be the only way!

Spinosad will kill thrips without killing you.

I have been experiencing the same problem after a thrip infestation. They seem to have diseased the plants. I recently tossed my strains because of this and began again from seed.

That's entirely possible as there are several species of thrips that are virus vectors. Thrips Vectors of Tospoviruses The biggest problem comes in trying to positively identify the disease. Not many growers have access to these tools:

“Three commonly-used techniques are double antibody sandwich-enzyme linked immunosorbent assay, reverse transcriptase-polymerase chain reaction, and mechanical sap inoculation. Additional serological and molecular methods are employed when thrips screening is needed. Double antibody sandwich-enzyme linked immunosorbent assay (DAS-ELISA) is commonly used in tospovirus detection.

Spinosad is very effective at killing thrips.

I will try also with spinosad...after using "Dislike" from Aptus...taken by a friend, but seems to be only repellent.

Spinosad kills also larvae and eggs??

I'm sorry Fdupp for your strain! I'm trying not to loose mines!

Spinosad wipes them out. I would spray everything down, then do it again a week later to kill any survivors. This worked for me as I havent seen one since.
