well first and foremost you NEED a thermometer WITH a humidity reading on it - this is a must - you can pick them up for around $10
second of all - you want your fan to be blowing in a OSCillating way onto your plants - not DIRECTLY onto it - just have it occasionaly blowing onto it - too much...
well, for a first plant its looking very good - the stem of this plant looks very strudy and healthy so props on that - has a nice width, height to it!
how long did you VEG for?
+ REP since its your first grow - keep @ it buddy :)
