So I'm getting spots on leafs and it's progressing pretty fast also the pot is staying wet longer than normal. I'm growing in coco with grow dots in 3 gal pot and I'm giving it sensi cal mag xtra every watering at a ph of 5.8. does this look like a deficiency or lockout?

Calcium deficiency. Add cal/mag to your line up or increase the dosage if already using it. Remember, what is showing in the leaves now, is a direct reflection of what was happening in the root zone 2 weeks ago. Cure will take 10-14 days to show results, it won't happen in 2-3 days. Damaged leaves will stay damaged, but new growth should be fine once you start giving extra cal/mag.
