.3) Reflector type? bare bulb
.4) Is there a consistent fresh air supply? yes
.5) Do you have an exhaust fan and a circulation fan? yes
.6) What are the bulb wattages, kelvin ratings, and schedule? watt 23 or 26, higher spectrum i think 5000k (can't remember and they're off atm), 16 on 8 off.

13) Specific brand and N-P-K ratio for each bottle. canna brand terra line(tera vega 2-1-3 cannazym 0-2-1 rhizotonic 0.6-0.0-.0.6) feeding schedule is a bit of a mess atm will go into more depth in the post.
14) How often are you watering between feedings, and how much per watering? feeding schedule is a bit of a mess atm will go into more depth in the post.
15) Any additives or tea's? no
16) Are your ph levels stable, or do they fluctuate? pretty stable i think..

Watering

9/7/10 ph 6.3 ppm(didn't measure probably around same as second watering)
9/10/10 ph 6.2 ppm 70(ph'd down then up'd used to much ph down)
9/15/10 ph 5.8 ppm 230 little less then half strength on the nutes
9/20/10 ph 6.0 ppm 300 tiny bit more then half strength
9/25/10 ph 6.2 ppm 20(just tap water ph down'd)
9/28/10 decided to flush two(flush water ph 6.3-6.4 ppm 20) and give them 1/4 strength nutes and give other two 1/4 strength nutes 6.3 ppm 160 (1/4 strength from the canna guide)

picture time
Front left and back right were the ones i flushed and gave 1/4 strength nutes
(Broken off tip was my fault that leaf did fall off when i barely moved it though here is a picture this is of the back right plant again

Oh yeah on watering i water till slight run off

[canniwhatsis]

Looks N deficient, What's you lighting schedule? I guess by the pics your still trying to vege them?

CoCo doesn't have any nutes,... so YOU have to feed the plants,... Looking at your feeding schedule (or lack there of), I'd wager that this is the source of the problems.

I've got no experience with CoCo,.. so that's just my "Gut" feeling,... hopefully one of the many experts will chime in soon!

[OaklandCA420]

looks like a low ph problem. do you have a solution to raise your ph? your ingoing water ph should be around 6.5 to 6.8 plus adding nutrients will lower your ph.

[Layzee]

the roots organics has coco fiber, perlite, pumice, worm castings, bat guano, kelp meal, greensand, soluble kelp, leonardite. it doesn't list any specific ratio what i found was it has a starter charge. so i didn't know if i should give more nutes or not. and for the ph i was sorta shooting for the middle of what the roots organics bag said for ph,and what the canna guide said to, haha.
