Seedling in Coco problem

Hey everybody. I hate starting a thread for something like this but I am at a complete loss and am hoping someone can point me in the right direction.
I've got a few succesful grows under my belt in soil, and this time thought I would try coco because I like how much control you get over everything.
So heres what i'm workning with:

Seedling planted in 50/50 coco perlite, coco is botanicare Ready-Gro, perlite is plain pro-mix. Seedling is 11 days since sprout, and I've been giving it PH 5.8 tap water left out for 24 hrs, have only had to water 2 or three times. For lights its under 4 26 W 6500K cfls (with 2 other seedlings(, have fresh airDSC00140.JPGDSC00141.JPG DSC00142.JPG DSC00143.JPG
When I watered 2 days ago, I noticed the leaves start to droop a bit within an hour or so. Later that day I also noticed that the plant was turning light green, and the original round leaves at the bottom started to turn yellow. I took this as a sign that it was time to start feeding.
So this morning I watered it until it had a nice runoff, my mix was 1 L water, 0.5 ML calmag, 1 ml each of COCOS a&B (1/4 strength).
Just got home from work and nothing has changed, its pale green and droopy as hell.

Hoping someone can help me out here as I have 2 seedlings behind it that I don't wanna run into the same problem with.

i grow 100% coco, I would say first thing is use a party cup to do your seedlings, and cut a bunch of holes in the bottom. that will help wth your drainage. you want more vertical space for the main root to go down. better to have a tall and skinny than a short and fat at this point. i would transplant, keep hitting 1-2ml a&b for a week and i bet they start taking off. get some root booster, i use H&G and find it well worth the price.

I hear ya on the party cups, I picked em up too late for the first one. I am gonna try that root booster though, thanks for the tip. Also i'm gonna try switcing to filtered water I just checked and ppm is 80 outta the brita and 160 outta the tap.

Don't overwater. They don't really look that droopy to me. Bump the calmag. Calmag is your friend. Coco requires sufficient quantities of it! PH and Calmag are the keys to coco success. Obviously there are other variables, but those 2 are key elements.

On youngins like that, less water is better. Bottom feed and feed around the perimeter to get those roots to reach out. Also prevents damping off.

I'm more in the camp that coco = hydro. you cant really overwater in coco, you just waste your nutes by blowing it out the bottom. I use H&G a+b, drip clean, root boost, bud xl and bloom boost. put it on a blumat dripper, and keep the ppms down. always run at 5.6-5.8. always slowly dripping. i do get the occasional blowout so there is run through occasionally, but maybe 4 times a grow. i know, cool story bro, but that's the diff with coco. on soil i would agree on the water 100%. I did 3 grows in soil, now on my 4th coco grow, and coco is a producer unlike anything I ever did in soil

heres a comparison of coco jiffy pellets on the top and peat jiffy pellets on the lower, strain is romulan x nl and both trays have been treated exactly the same, obvious the coco is performing better than the peat, pic was taken todayIMG_1424.JPG

Hey dude I took your advice and increased calmag to 1ml/L and fed this morning, this is the happiest ive seen the plant yet. bunch of new growth happening.
also gave one of my smaller seedlings that was showing yellow and its taken off too.
Thanks to all who replied, this website kicks ass

ohhh ummm im south of the equator where wombats roam, i use this http://www.biostim.com.au/myco-gold.html they also stock a similar product called trichoguard, its all good gear, i use the mycogold more often, my outdoor area is filthy with root rot fungus diseases so its an ongoing battle, they post worldwide & you can pay via paypal too... you may find a local version near where you are but this is the most economical product of its kind in my area
