First grow ever. GSC (Jazz Cabbage)

I believe I started germinating the seeds around the end of May. So for the sake of argument (between my wife and I), Plants began around June 1, 2020. One plant is slightly smaller. Lower leaves are yellowed and dying off. Plants seem to be growing well. Seeds are from some Bud I received from a farmer that was producing for Medical canibus markets. This is the first time I have grown canibus. I have forced myself to get started by germinating seeds when I was getting my vegetable seeds ready. I have a 4x4 DIY grow booth, made from 1.5" foam with 2x3 boards to make them into panels that I can then screw together to change the size of the booth. I them put panda film on the inside to line it. Still need to make a few modifications, however I can now control my temp and Humidity better. Next to go in the booth was a small Feit Electric 86W LED Full Spectrum grow light. This light is way too small, It will work ok for either Mother or clones, I think.
