Also If in coco I find too larger a pot can over can cause similar lockout issues. Good luck.

they are about 25-35 days old (youngest - oldest) and my starting water is 6 ppm (RO water)

I assumed you were in coco...lol my bad. What are you using? People have great results with only the micro and bloom...have you heard of the head formula? I used it for years and years and had great consistent results. Only switched recently because I was given a shit ton of veg+bloom and I’m loving it. But yea at that age, in coco, you could easily be feeding 1.0 I’d even go 1.2

That would explain your Ca/Mg deficiencies. Increase to half dose and see how this goes for your plants

uped the calmag a little and uped the nutes as well and that seems to have fixed it for now, they got there weekly flush today and are def looking better and the UK cheese that had serious cal mag deficiency signs has stopped getting worse
