Bottom eaves are drying up?

The bottom leaves on a few of my plant are starting to dry up. Ie: yellowing, yellowing with small brown spots, and turning limp.

I would have pictures up but my Mother#$%^$ camera is broke

Plants are 3 weeks old( 1 week rooting the clones and 2 weeks in veg) under 8bulb 4' long t5's. I am using Fox Farm Ocean Forest in 2 gallon bags. I am watering every 6-7 days. Water is 6.6-6.8 and using Fox Farm Grow Big and Superthrive. 1 tsp/gl of grow big and 1/3tsp of ST/gl.
any ideas?
I will try to get a pic up. thanks for any and all help guys.

Sounds to me like your plant is just thirsty... Every 6-7 days for water is pretty spaced out, try every 3 days... (twice a week)

Give it some water, it'll perk up again in 30 minutes.

+1 on the last post....your leaves should feel smooth to the touch, not crispy or dry. Even with a nitro deficiency, they will be moist while they yellow up until they brown.

Thanks guys. Which brings me to my next question. How much should I be watering them? This is my first soil grow, I have done Hydro with great success but I just don't have the time. I have been watering 27 plants in 2 gallon bags with 1 gallon of water. So that is like 1/27th of a gallon.. How much should I water them?

I watered all 27 plant with a combined 2 gallons with The Grow Big and SuperThrive. I will monitor them closely and look for changes. I am going to buy a new camer tomorrow and will post some picks..
Thanks again fellas..

Im no expert but You need to use more water, you want a good amount of runoff everytime you water.
Its better to overwater and let it dry out, than constantly water with small amounts.
