So out of all the info on thrips that I've found they all seem to deal with the eradication of the adult thrip. I know this is important because they make new babies. But to me it seems that the adult doesn't cause the damage that the larvae causes. I have only seen one adult in my grow but i have found that the larvae are everywhere. You need a good scope like you use to see the trics. For me I noticed that some of the lower small buds looked like they were maturing too fast, or like someone singed off the hairs. The naked eye sees nothing but with the scope you will see hundreds of little worms with front legs sucking on the buds. I thought they were only on those small buds cause there not on the big main buds but after checking my mothers (which seemed to be suffering from heat or lack of airflow) and the mothers were loaded with them too. the slivery patches are only made by the adults, I have no silvery patches. So how is one to know they got the thrip without the silvery patches or if you don't see the adult. If new growth looks stunted or slightly yellow in veg and the leafs look wilted and heat stressed or your buds are maturing or drying on the plant way too soon you might have the thrip. Still working out how to save my mothers and finish the buds so I don't have them next grow. no one wants to smoke bugs!
