Newfies first grow

Had some trouble early when I got the clones about a month or so ago, first watering my ph was off a lot and caused plants to yellow and wilt. Didn't catch problem right away because I didn't think water was the issue. Got a ph pen plants started to recover but didn't look perfect. I transplanted the plants on March 22 from solo cups into 1 gallon pots with coco and Gaia Green dry organic amendments and a small amount of perlite. Soon after transplant I noticed the yellowing returning but not wilting and showing signs of a calcium deficiency, picked up some calmag and after feeding the plants the colour went back to normal after about 4 hours. Started low stress training on April 6th and plants look to be talking it well.
