First Grow, Need some help *Pics

Alright so the past couple days haven't been so great. I haven't noticed any growth the past couple days when usually I can notice growth everyday. The leafs are curling on one plant, and on another there are a few brown spots on the bottom leafs. They are about three weeks old now. I water usually every other day, or whenever they drink it all, and set the pH of the water to 6.5. I have four CFL lights each 1700 lumens on for twenty four hours. I also have a fan that runs for four hours a day at separate times. Is the problem that they are getting too much light, or is there a deficiency? Thanks everyone. Sorry if the pics are bad quality

Anyone? Also, I noticed the stunted growth right after i transplanted them. I'm 100% i didn't mess up anything on the plants, could they be in a shock sort of state?

nothing wrong with 24 hour light, your ph is pretty high, try to shoot for 5.8-6.2. i doubt its a deficiency, whats your feeding sched like?
Likely culprits are overwatering, ph imbalance, or just plain old transplant shock. Be patient, get your ph in check and they should probably turn around.
Good luck and happy growing!

I usually water every 2 or 3 days, or unless I notice the soil is too dry, even at the bottom
