Great pics and info. I grow in canna coco, and have been adjusting jacks mixes for years. I use pure ro, and pure coco. I just can't get my veg formula quite right. I have found almost all my strains need more calcium than standard jacks 321 provides, and I often struggle with mild mg def in early veg. I am now running jacks in the 3/2 ratio, but not adding any epsom. Instead I am adding calimagic, starting with 3-5ml/pg before adding jacks 5-12-26, then calnit at 2g/pg. Plants seem to be responding well, but I have learned not to get my hopes up. I am close to switching to something different (besides jacks) for my veg and mothers. Previously (before calimagic) I would have to add near equal parts by weight jacks and calnit and varying mg to get decent results. It's been frustrating trying to get things dialed.
