Herb Insect damage, need help

I am new to plants so I'm not entirely sure what to do. Of course being herbs, I don't want to spray chemicals of any sorts onto them to kill the insects. The herbs I have in a long pot include; Purple Sage, Hot & Spicy Oregano, Moroccan Mint, Yellow Thyme and Rosemary. I am planning to move the Sage and Rosemary into bigger pots or into the garden at some point.

I know I have leaf hoppers, they started off on the Sage but they're now on all plants (I think). There may be some spider mites, because in the Thyme there is some very fine wispy webbing. I was thinking of purchasing some Lace wings for this problem. Do you think that will work?

Also, am I still able to consume these plants if properly washed etc..? I'm quite sceptical so I've only been picking leaves without damage on to consume. There is no damage on the sage (although the sage was attacked by powdery mildew at first which I have managed to handle with milk and water for the time being, I also think the hot weather at the moment has slowed it down from returning)



Any other advice I will appreciate greatly, thanks

 

I think that is damage caused by thrips.

 

I don't have a magnifying glass, but if they are Thrips how do I get rid of them? thanks
