Hello this is my first grow Judy Checked on my plants this morning and found about 5 little thrips on the leaves of my plants. I have been using Safers insecticidal soap with potassium salts of fatty acids it worked pretty good in veg while I had the plants outside for a bit. They have been inside for about 30 days now no problems at all. Put the plants on 12 12 about 18 days ago I inspect them everyday. Yesterday i noticed a few on my bigger plants took them out shook the hell out of them sprayed the soil top with the mixture i made but pretty iffy on spraying the bigger plants at all since they got a decent amount of pistils now, is it too late to use a potassium soap insecticides as a foliar to drench the plants down shake them off and dry with a few fans? Or will that cause me greater problems then the thrips and if it's too late for that are there any alternative methods? Here's a few pics
