spider mites and sm90

[oldandintheway]

I am currently in the mid-late flowering stage and I now have spider mite webbing on one of my plants. I removed all webbing I could and dusted all plants with diatomaceous earth. I read on another forum that they said dilute the ratio 1:5 and check ph. My question is, will the sm90 harm the flowers or is there something better I should be using?

Gayrd,I need more info is this a indoor or a outside grow? D earth should b sprinkled on top of soil and around grow room if indoors,and should b repeated with each watering .ive never never dusted my girls with it but it couldent hurt im doing a out door grow now and use pure neem oil mixed with water and sprayed all over plant under side of leaves too and can b used up to harvest safely about every ten days or so more if needed.
