The middle number is all phosphorus. I think it was too much. Maybe just use the dynabloom for veg perhaps next time. It looks like it could be deficiency, but it's hard to tell exactly because I haven't seen so much P fert given all at once. And yes, there could be some missing nute like calcium, but unless the leaves and soil are taken to a lab and analyzed it is impossible to know what happened. Most people go easier on ferts and this is why I suggest people use happy frog or other soil that has fert in it. I swear, I'm going to start making my own potting soil with fert mix and sell it cuz it would make life so much easier. Anyone up for that? If I make a mix and package it, would this interest anyone out there?
