CalMag issues seem to be finally under control. Better late than never. Major changes needed for the next run, most likely saying goodbye to BioBizz Light Mix soil, can't deal with the amount of bugs anymore.
I understand you completely, I used to feed my plants with the full dose for photos and I always wondered why the tips were burnt even though I gave them half the recommended dose. Every manufacturer has prominent feeding charts but i didn't know it at that time.Good luck bro and happy growing.
@Whitewizard, I tried to flush it for 2 weeks and now it seems to be "better". At least I learned that autos don't seem to require nearly as much nutrient as a non auto. Also, my local water is soft AF like I've never experienced elsewhere.
