mites/thrips

hi i have tiny little white pests i on the under side of my plats what do i do help need NOW

well are u in vegg or flower. If u are in vegg and the plant is small do soapy water and rub lightly under the leaf. Do this a couple of times as these creatures can hatch in 5 days. So 4 or 5 applications would be proper. If u can rinse say 20 min later it is cool aotherwise it will be fine. Think about it though, u have to clean the soap scum off ur tub. Spray underneath too, I think u know this. Also, keep the area clean. I have a shop vac and vacuum around the plant. They are bitch. I could use more info. If u are in flower u can use soapy water, but u can also mix hydrogen peroxide(H2O2) and water. About 1 to 3 depending on how bad u want to kill them. Will not hurt the plant. With this method I recomend spraying once a week as it doesnt seem to be as officient.

Sure they aren't whiteflies?

my cuttings are only a few weeks old they are very small at the moment if u can get on to my profile there should be a post from last week or the week before that has pics of what i thought was a nute problem but found out tonight was pest sucking the nutes from the under side of the leafs

Hi mate

the best way to beat thrips/white flys is place perlite over you soil this interupts the matured thrips/WF breeding cycle.
I also sprayed my plants once a week for 3 weeks with a chemical bug spray for tomatoes.
To kill off the flying white flys use them sticky yellow cards you can get from any hard ware store

Try post some pics if you can that way we will be able to judge what your problem is a bit better.

hope you get it sorted
