and it should be worth your while. You could have it on 20/4 until your autos are done then put your photo into flower! By then if all goes as smooth as it's looking so far, your HPS should have ALREADY paid itself back. Best of luck buddy!!
Also with your intake and outtake with computer fans I still recommend at least 1 fan blowing directly on your plant. Not only will it help with temps (the hps wwill kick off far more heat) but the stems, alot like muscles, will become stronger by being blown about and therefore able to support heavier buds.
So jealous man, I gotta wait 2 weeks for my hps Light, tent and ventilation to arrive. But my cfls certainly do seem to be cutting it for now...
have you tested your ph yet? That's looks like multiple deficiencys from a lockout to my noob eye. Also I think I can see mite damage. (the white specks eeverywhere) flush your soil with phd water, if you don't have a test kit and ph up/down then find bottled water with the ph written on it. Your aiming for around ph6. I hope I help you mate, I had a similar problem a free weeks back on my photo strain and it was because my soil was ph 8.7.....
