Not sure what you mean by "Not too long left...". How long before you plan on harvesting?Checked em yesterday. Mites on the fabric pots but can't see nothing on none of the leaves. Not too long left so hopefully they be OK I spayed pots with bug stuff so hopefully be ok
There are several sprays available that will help get rid of mites and they can be used right up until the day or two before harvest.
Everything you do now to get an insect problem under control will help when you start a new grow.
