Well, after 3 years of growing indoors, I've finally got thrips in my mother tent. I spotted a few leafs with pitted areas that were grey/whiteish ... got the loop out... thrips. Bounced over to the Garden Supply Center and got some Captain Jacks. Sprayed the tops and bottoms of my mother, and clones. Thankfully, the main grow room has been empty for the past month or so, but it might be a good idea to bomb it before the next run which is starting in Oct. I hosed down the tent from top to bottom. Hopefully, this will knock em out. I think I caught it early. Im not a fan of spraying while the lights are on, but I wanted to get on top of this. So I turned the lights down to 20%, and will wait another 5 hours before they go out and turn them back up for the 6 am awakening.
