There's only 3 plants now...the fourth was damaged so bad by these pests before I realized it that I had to cut her down (I normally only start from seeds and have never had any pests in my garden but I was doing someone a favor and took their clones in...they didn't even know they had a problem). I only have one in flowering cycle, but she hasn't kicked out white hairs yet. The other two are clones 3-4 weeks old. Captain Jack's with Spinosad is what I've been using. The thrips have done some damage to all 3 plants but no damage that they can't recover from. I'm spraying every day and I'm not seeing any more of those buggers but how much longer should I spray? I still have one clone that has been quarantined from all the others but I still sprayed her too...roots are starting and I have to put her in the tent soon. Pics below...
