Week 2 pretty boring. I had an emergency I needed to attend to that forced me to leave my plants in inexperienced hands for a little. I did a lousy job at buffering the coco. Due to that my plants suffered early calcium issues due to the cation exchanges taking all available calcium. Once I was back in town, I began giving high doses of calmag feedwater along with foliar feedings of calmag. Until the exchanges are satisfied, coco will continue to take calcium leaving your plant with very little. This is why I gave calcium to the coco via feed water as well as foliar calcium for the plant.
