Plants Are Loosing Their Green?!!!!

i am using Botanicare. i am following the label and using with every watering. i was going water/feed/water/feed, and that was not working properly. so i went the direction route. i noticed about the 3rd week mark some of my plants were nice and a rich green. almost that nice and shiny high contrast green. im heel colorblind, so my color descriptions may sound a little amusing. i can not really describe it. but the colors were not very consistent. all the same Plushberry plants had green in them, but not all. i though maybe i needed a little bit more nitrogen to my mix and i did and that looked liked it helped. so i increased a little bit more again the next week and now it seems as if the color is fading a little. i was under the impression that if you are loosing green, you have a def. when you have a def, is it safe to increase nutes?

also, the info you will need to evaluate my situation. Veg: 18/6, on week 5, height: about 6"-8", pH: 6.7-6.8, soil: Roots Organic 707 Blend, temp: night 68-72, day 72-79, humidity: day-35%, night-70%+ (i know my humidity levels are kinda fucked. its so damn dry here and i really need a room controller and humidifier.) 1000w Metal Halide, about 12 inches above plants. have 2 small clip fans in a 4x4 tent. exhausting with a 8" C.A.P. fan.

if any other info is needed i can oblige. much appreciated in advance!!!!

Shouldnt need more nutes if plants are that young in 707, that seems early for the size of your plants to start supplementing N. I'm thinking that 1000mh is burning the shit out of the plants, but w/o a
pic I'm just pissin in the wind...

nah, i see the green today. i dont know. im super super super UBER colorblind. so im fuct all the time. like this week. i see the green! but im having other issues with new tent, venting and fan size to port ratio. i will have blood dripping from my forehead within the hour, im sure of it!

thanks for the insight. and nah, the 1000w was starting to burn my 2 plants that are over the 1' range. but the others that are about a week behind, the ones that didn't get pushed as hard, are fine, the 2 tall ones i started early started to get a little burn. i moved them from under the light the the farthest edge of the tray and they seem to be rocking. i shit you not. its like 50 days old, about 12-14" and has at least 24-28 tops!!! its fucking amazing!! but the other 25 are just growing normally.

ill try to post a pic today.
