Hi,

done a substantial amount of reading and have a problem i'm a bit perplexed with as a few possibilites present themselves.

helping a buddy do a first grow in this setup. previously have done outdoor quite well, and indoor twice many years ago (but that was soil). this setup is duped from another friend's very successful setup using same everything down to the clones' mommy.

First plants are under 2 x 1000w hortilux's, air cooled hoods, sealed room, ac unit w/ condenser intake and exhaust (79* day, 74* night), dehumidifier (holds at about 50% +/-) co2 (holds at 1500ppm during daytime), running cutting edge solutions, bloom, micro, plant amp, and uncle john's blend. clones (lavender purple) were vegged 8 days then kicked to 12/12. i flushed with water when i switched and cleaned the res, etc. ph is about 6.2, nuit ppm 950, water temp 76*. plants are in pure canna coco on tray that fills once a day.

i thought the problem was over-watering as the coco sure holds it andi ran the timer a bit too long in the beginning so they haven't had any water for 5 days and now the coco is drying out. i foliar fed half yesterday with epsom salts in case it was a mag deficiency but i haven't seen improvement yet. pics are attached but are under hps light so sorry about the tint to them.

as you can see the plants are too small for the age and growth has slowed tremendously. leaves are yellowing from the tips inward and eventually dying. many dead ones have been removed already. roots (looking through the bottom of the pots) are white and very fuzzy. look healthy. stalk down where it enters teh soil doesn't look discolored at all. solution is a week old at this point and has a circulating pump as well as 2 bubbler rods in it. no bugs.

any help would be greatly appreciated.

Thanks a million.
