Hey BC. Theres alot of the fuckers, let me tell you. First I thought I had some sort of a Deficiency, with the spotting. I have been upping the Nitro and Micros for some time with no improvment. I didn't even think to look for bugs, as I just got rid of fungus gnats a couple of months ago.

Defiantly sounds like thrips. Their larva are small and have a yellowish-white color to them and leave black and clear spots on the leaves from eating damage. I have had them for 2 grows now. I use a garden-safe spray during veg. to kill most of them, but I'm sure neem oil will work. I hunt them with my fingers too. Im going to try adding the sticky cards =) , I have the hanging ones for flys. So far they have stuck to eating the leaves and havent touched the buds. They also havent caused too much damage to the plants as long as you keep their numbers down. GL

Yeah, I think thats what they are as well. I've purchased some Avitrol EC, an over the counter pesticide available at your local gardening supply store. I applied it this morning after my lights turned off, so Ill tell you how it goes ina few days. I too have also hung sticky cards, and while Ive caught a hell of a lot of fungus gnats, I dont think I see any thrips on there.. Fuckers are small though, and the plants dont seem too damaged at all, in fact, they look pretty damn healthy, but, I dont want to just take that for gtanted, maybe they just havent gotten to big enough numbers yet. Anyway, I will respond back on the pesticide, my next step was going to be some type of predator bug.. Has anyone ever tried plain old rubbing alcohol or soap and water? They are supposed to dry out the insects bodies and kill them by dehydrating them, but it sounds like it may be harmful for the plants (the alcohol more than the soap and water)...

When dealing with thrips dont hang the cards, lay them under your plants, I lay them on the pots and they catch a ton of them. If you are hanging them hang them as close to your plants as possible or the cards dont catch that many thrips.

do you use the yellow or blue cards? Have you noticed a difference between either of them?

I only have yellow, never tried blue. The yellow seem to work fine tho. Maybe buy a pack of each color?

I bought a pack of yellow, but I was searching online and the blue ones actually say they are for thrips, as the yellow say aphids and whiteflies.. I have noticed A LOT of fungus gnats, and maybe a couple thrips. I have them hanging but down below the canopy, off the bottom-most branches.

I bought a three pack of raid fumagator foggers and they have a 12% of Permethrin. It says to remove house plants from the room, but I the guy at the store said I don't have to. I used one of them with a couple of test plants in a room last night and there wasn't any problems. It killed all the thrips I saw and I couldn't find any live ones. So then I fogged the entire grow room 4 hours later. I fogged the veg room this morning. This should controll them for a while. If I see them return, I may have to do it again in the weeks to come.

For now I seem to be free of them. I just wouldn't want to smoke this weed for a while.

Some plants were two weeks in, others a month. But 7 of them were flushing in thier last week before harvest.

I'm going to run them under the shower tonight to help rinse off what I can.
