Everything is looking good. I am currently using foxfarm soil as well and I didn't use any nutrients at all with my seedlings because people say on here a lot that foxfarm can be a "hot" soil for seedlings because of the nutrients already in the soil. FoxFarm has 30 days worth of nutrients for your plants and after that I would start using nutrients. I did it this way and I have yet to see ANY problems with my ladies at all. No nutrient burn or anything. My temps are simliar to yours and i am also using CFL's but two "big" ones, x2 85 watt CFLS. Like I said prior though looks like your doing a good job with everything else just don't worry about having to give them nutrients right now they will suck up all the pre-nutrients in the soil already for the next 30 days. + rep + sub
