Star Pupil by Mass Medical Strains

D22 - 10.8 - She a cute lil bush D24 - 10.10- Suffering from an unseasonable heat wave and fighting to keep temps down. Young star pupil appears to be handling it ok. D26 - 10.12 - I'm scared spitless right now. I found what looks to be broad/russet mite contam on some nearby plants. This Star Pupil don't seem to be affected but I'm treating it along with the others to make sure. I've treated with insecticidal soap and neem oil the past two days right before lights out. Plan: treat with some heavy duty stuff to be procured today. Predatory mites and lady bugs on their way. Will release them as soon as they arrive. I want to use some diatomaceous earth, but I'm afraid that will counter my predatory mites and lady bugs?? Help! Taking any and all advice on getting this shit under control!!
