Hey Growmie,
Looks like you have a spider mite problem. Before your first treatment….Cut down their numbers! Control the heat, Have lots of air blowing over the plants and top of growing medium spray spider mites off the plants if you can
Spider mites like the heat and hate a windy environment. A cool breezy grow space won’t get rid of spider mites, but it makes it harder for them to reproduce so your other control methods are more effective. If it’s possible for you to bring your plants outside or somewhere safe, you might even consider spraying off as many spider mites as you can, to get their numbers down before you start your main treatments. After doing this you'll need to use something like an Insecticidal soap or alcohol and Water mixed together (9 parts water to 1 part alcohol) will also kill the bugs on contact and shouldn’t hurt the plant. You will want to use a spray bottle or mister. You can also use neem oil too. Hopefully, I answered your question and remember " Happy Growing and Free your mind one puff at a time ".
