First Grow with Pics, Advice?

First time grow.
Clones (3 Lemon Kush & 3 Bubba Kush) had a very well developed root system (they are 4 to 5 weeks old) when planted in 5 gallon pots with Ocean Forest FoxFarm soil. They were placed under a T5 fluorescent 4ft-4 with 2 supplemental CFL lights and a large fan circulating the air. So far they have had a 24 hour light cycle, but I'm thinking about switching to 18 on 6 off. They have been getting about a quarter gallon of water a day, keeping the soil nice and moist. I do have a question about run off. Do you leave it in the saucer to evaporate or empty it to avoid mold? Basically since this is my first time, I'm wanting to know if they are looking good. I've noticed a few leave tips turning brown and wonder if the lights are to warm, to close (they are 4-5 inches away) or if they are not getting enough water. Also, there are a few yellow patches with some wilting leaves. Any suggestions? No chemicals have been used. No anit-wilt or extra fertilizers. Theres a pic of each clone and a few up close pics. Comments please.

clones obviously? Looks like when you leave them too long in the humidity dome with no nutes. Start feeding her. You should see the new growth come in nice and green.

Cowell is correct, theose plants need food. You should also check the soil pH asap.

Be sure to let at least the top third of the soil dry out completely before each watering. You are watering way too often.

I was thinking PH too.. to me pic 2 looks like a mag def. But I figured that if you weren't feeding nutes.. there's nothing to lock out... guess I learned something new today too. Thanks MF.
