ya i tried attaching it to the post. I wonder what happened 😬

So this stripe on the leaf showed up on one of my other plants. 🤔🤔🤔

I grabbed a microscope and searched but didn't see anything that resembled a spider mite. Or at least what I to believe spider mites look like and the other signs of them being on the plants. I havent started giving the plants calmag yet. Do you think that could be it? 🤔🤔 they have the slightest purpling to the stems. The only reason I've been putting it off is because I haven't gotten my osmosis system yet and when I ph my well water its at 6.7 and my ppm after I added the calmag shot it up to the 900s.
