1st real grow...and 2 problems

well these are my 2 g1 plants im growing hopefully their females.any ways....
i already know part of the problem .it pretty hot in their but not to hot i never let it get over 85 F...but they look like they have some rust spots on the leafs...
my grow area has a 1000w hps... in my closet while i wait for my grow tent.
the 2nd problem on the other pics as u can see looks like is longer on one side its wierd...and the nutrient im using are cns17 commercial nutrient system from Botanicare (grow 3-1-2) is says on the bottle to use 30ml in 4L (1gal),but the guy at the plant store to always use half of what they say..(i dont know if its good info but i did it)
the plants are about between 3-4 weeks.
and the soil is foxfarms ocean.
