So I've just started week 3 of my dwc grow. I'm a beginner so still learning. I have 2 questions. First one is I'm starting to see some clawing on one of the leaves and unsure what's causing it. Secondly the right rear plant has always been stumpy. Any ideas what would have caused that? These are feminised seeds of the same strain. I'm currently using the GH flora line with all the supplements and feeding using the expert recirculating feedchart at 50% which is about 650ppm with a ph of 5.8. thanks
