spider mites....ladybugs in orbit...what else?

So my issue started a few weeks ago and since I've only been doing this a few years now I had never come across the signs of spider mites i.e yellow pin point dots on leaves. So this started about twof weeks ago to only half of my plants? very strange....I'm in a 30 day cycle so the oldest ones are 30 days ahead of the youngest ones and had absolutely no issue....

At first I assumed ok....it's pk burn because I was really pushing PK on them, and without researching, I let this continue for 2 weeks...yes...I am aware that this was a serious rookie mistake.

So as the title states, I bought 1500 lady bugs yesterday and they are going to town. My advantage is that the room is completely sealed and filtered in and out....I personally brought the mites in from a friends garden....

Is there anything I can spray as a knockdown to get some immediate relief WITHOUT HARMING THE LADY BUGS?

I'm literally in there with a qtip getting all the noticeable egg patches lol. This will be a costly mistake I can feel it already. Wondering if I should get 1500 more lady bugs and just bomb the room with them

Bombing while the lady bugs are in use will just kill them too so if your going with a second wave start it after the ladybugs have done their best.
