couldn't find exactly your ventilating setup. I've seen computer fans but can you please take pictures?
idealy you would have the passive intake at the botton, the internal air movement fans (your pc fans I guess) blowing air upward and shaking the plants a bit and the outtake right next to the bulb like i've seen you do.
if you pull air out there will be a negative presure.
by correctly ventilizing the grow room you can lower the temps quite well.
cool tube is awesome. I've purchased one from my hydro shop and its a great thing.
however mine cost a fortune so I got a hang on 2x 6" glass pipes in the right length for next time I'll need one of these ;D
in your size of grow room it will make a huge difference as you can place your light with a good cool tube (even a 5" one) about 25cm away from the plants without burning them resulting in way more light usable to the plant.
at that size my plants took about 150% the recommanded nutrients. the magic is to introduce it over time. (now they take about 200% the emount, and only because I cant efford more ferts. I could easly gave em 3 times the recommanded emount by now)
BUT I AM NOT FAMILIAR WITH YOUR FERTILIZER SO I DON'T KNOW HOW THE PLANTS WILL REACT.
just know that you could probably try increasing the dosage by 10% each watering. and stop when the tips of the leaves starting to burn. if they do burn a bit its really nothing to be afraid of.
PH should be around 6.7 and unless you know your water supply and nutrients well enough to know what will be the outcome PH. I don't.
