If you don't mind me throwing words out their. I am fairly new myself but I noice some things. Your rh is low, is it because the cab is open? I like to get to 60% in a non co2 environment.
Your plant looks under lit, and over watered. Theirs something off. Your starting to get a droop, and the new growth is coming out droopy also. Maybe its strain. Again this is just what im seeing.
Those are incandescent? Glaze coated? I don't know how effective thouse are and what spectrum that glaze cuts out. Can I suggest a cfl made for growing, aka sunblaster. If your like me, finance holds me back from doing what id like to do a lot of the time, but if I can I would love to see you with a powerful cfl setup or move to hid. LED your asking for headaches. Judging by your grow tent temp you live in a colder climate...?
