"Rookieness" meaning I've only raised one plant through harvest and got plenty high. But I considered myself mostly lucky on that grow. I never had issues w/ leaf discoloration of any kind. Also, on that grow, I used only A19 style LED bulbs; 8 of them in the 6500K and 2500K range. They seemed to work well in veg. But, in flower they weren't sufficient. My yields were poor. So, for this grow, I will be employing two proper grow lights(in my sig). I've been using a pH pen. On my 3rd grow, I want to address my soil composition. I just don't know what I'll be using yet.
