This is fine for a first grow but the second picture tells a thousand storys one been the light has been too far above the plants you want the light has close has possible.this can be a little dounting at first but belive me they will get accustom to the extra heat if there is any.put the fan between the plant and the light so the fan is blowing cold air across the gap between the light and your plants.it is not too late though yournext grow get them lights inces of the tops of the plants you will be getting a nice few ounce then instead you will be lucky to get a ounce dry.lower the light down a couple of rings on the chain till you are around 6/12 ince of the tops this may get you a extra ounce or so.but the grow looks great apart from the node been so far apart you want dence nodes .these nodes will then join during the flowering and give you far more nugs.
