O.k. i'm going to start this with some background so you guys know what was going on. I'm on my first grow in soil. I had one of my four plants (northern lights) pop up and start growing out only one side, been like that since seedling and still is. I transplanted them from the solo cups to 1 gallon pots and about a week later someone gave me some advice to use cal-mag on them and i took it and did give them the full seedling dose of cal-mag. When i transplanted i broke the roots of the one that grew funky almost in half, she slowed down for a day and then seems fine. It was a few days later i used the cal-mag. The only other nutes they got was 1/8 solution of big bloom twice in the solo cups. no other nutes around the time of the damage but cal-mag, the damage showed up 5 hours after i gave them the cal-mag. I'm thinking it was the cal-mag but maybe coincidentally timed damaged roots showing their face. I really don't know so i'm looking for some input from anyone who may know. They are still growing great and i'm way ahead of many of my peers on their first grows, this one is just throwing me for a loop. The first two are birtha the funky growing plant and the other one is the only other plant to get damage. That one was totally healthy when i added the cal-mag and i did not damage it's roots on the transplant.
