need sum help, pics included. indoor grow!!!!!! too much fert or dificency?

im about 8 or 9 weeks into vegatative stage. indica plants. currently in 24 hour light, 400 watt metal halide. using foxfarms ocean forest soil, and foxfarms grow big and big bloom at half strength. i water with distilled water when the soil drys out and plants look a little droopy. ph is at 6.5 to just below 7. some leaves are turning a light green to almost a yellowish color. some stems have a reddish to purplish color..each post after this will be for a seperate plants with pics included to help... thank you for your help!

I would stop using distilled water. I don't think the ff your using covers all that missing in that water. I could be wrong just my thoughts.

plant 1- 15" tall, 13" wide...just a few are turning light green

those look better than my poor plant -- im a total noob, and would look at these plants as healthy.. interested to see what issue you have, if any..

plant #2- 14 1/2" tall, 13" wide.

plant #3- 18" tall, 12" wide.....you can see some of the reddish/purpleish color on the stem in one of the pics

plant #4- 21" tall, 16"wide, you can see in some of these pics that some leaves are curling up on the edges.

I've been using this page is a simple guide -- not sure if it's accurate or will help

plant #5- 18"tall, 15"wide. you can see in some of these pictures how some leaves are dark green with blotchy lighter green in them at spots.

plant 6- 18"tall, 17"wide

most of these dont look that bad at all..a couple i would say are just slightly unbalanced with nutes, feed with water for a week then try and rebalance your nutes better..nothing looks critical

plant 7- last and final plant- 23"tall, 16"wide.

thanks everyone for the replies! dalefthandman, i agree, i dont think that its anything too threatening at this point but i just want to make certain of the problem before i go trying to correct it. i plan on flowering in another week or 2..all girls are showing sex. its just that untill now all of the leaves have been dark dark green to almost a blueish tent.
