Do not use the fertilizer spikes they are way too high in N for flower. Get some organic bone and bloom meal if you can't spend a lot. Just to remind you though that if you don't put in a lot do not expect a lot back in return. The more you put it the more bud your plants will reward you with. Also I find it hard to believe that one CPU fan puts out the same amount of air as a box fan. I'm sorry to tell ya but your temps are going to be wayyyyyy to high if you don't get some proper ventilation
