In my small experience at this, you should not be feeding anything except ph water and maybe 100 ppm solution. At this point you may have some buildup in the rockwool i would just try phd water for a while. These are just seedlings right, how large are they. You may just want to keep that 600 far away for a while or try a flourescrent light till they recover.Hopefully some others can chime in.
good luck Grinchy

I stunted the growth of my plants the last time by putting the light too close (18") for 2 weeks. it took 2 more weeks for them to recover and start growing again. move the 600w as far as you can from the plants, wait til the 3rd or 4th set of leaves to come out before moving it down. judge by how much they're stretching and move the light down according. they don't need any nutes. in my e&f, i flood 3x a day for 20mins, 18/6 - 45 mins after lights come on, sometime in the middle, and 45 mins before lights off. they don't need to be drenched in water constantly. the hydrotons will retain the water.

Buy Advanced Nutrients Barricade instead of ph up, it raises ph while giving your plants some silicate something. definitely get some ph down, gh is what i use. get a tds meter. if you have money, buy a constant reader and an extra water pump for mixing your res, makes mixing easier.

Your plants look OK to me. Just give them ph 6.0 water till they start to grow well and you'll be good. Oh, and once you get the hang of hydroponic growing, you'll appreciate the amount of control you have. Good luck.

i'm no expert or anything but i think i'd kinda agree with haps no or very litle nutes for at least 10-14 days ,and maybe try to raise your light a good 12-24Inch more above your ladies that should do it. and try if you decide to buy some barricade don't use much it's a good ph up but its potassium silicate and its strong so don't use much unless you want to stunt your plants 
..best of luck with your grow.....Oh buy the way keep a Close eye on your Ph it looks your ladies might be suffering from ph fluctuation, but what do i know! best of luck

hunter wolf had said that barricade is all he uses for ph up and that it was hard to add too much. how do you know too much is too much? i rarely ever need to ph up.

when i use my full line feed in the specified chart than advanced nutrients provides the amount that you use ia about .17ml per liter in week 4 it's only 0.2 ml per liter the reason i said don't use to much is once i had to eye the barracade for my week 3 and i used to much ..my plants growth was stunted for about 1 week (they did nothing all week and looked like s**t) thats the reason oh and the top soil became very hard and crunchy.if you only use it for ph up then you don't have to worry but if you use it as an addative in your nutrient program then dont use much

THEY ARE ASKING!!!
they show a mag def to me.
some of them even have a midgrade mag def!
thats hardcore yellow/green leaf is symptom...
hydro sucks. too difficult, do a foliar with epsom salts.

You let the cubes dry out?
That will hurt the roots, and if you constricted and dried the roots out like this you're chances of healthy sprouts are slim...You also transplanted too early, I've used those buckets at least 20 times and whenever I transplanted that early (ie. tiny root structure) it was a crap shoot and I lost a few, some stunted and some turned yellow. Best bet is to use larger rockwool cubes, good brand like BCUZZ, soak thoroughly overnight in solution, and veg in the rock cubes in a flood n' drain for like 2 weeks, with daily watering schedules, never dry them out, ever.. Those are just too small to transplant into hydroton, just putting them in there tears up the fragile rootlings, and the fact that you dried them out.....no bueno.
I'd definitely monitor my ph well, and remember, too much PH up or down in the mix is toxic, too many adjustments and you just jacked the water, HYDRO is very finicky when the plants are weak, but when they go in with a foot of height and several internodes, they bump like a forest, IMO, you made some mistakes that have nothing to with a bad mix, but indeed nutrient blockout due to damaged roots and premature seedling transplant....
try over, you are wasting time with those sick babies....

I was super-geeked about growing, and did hydro for my first grow. It was a disaster, and now I do soil. MJ seems to be a pretty hardy plant, but in my (brief) experience with hydro, it was very easy to screw up.
In hydro, problems will appear much faster and you must know how to respond to those problems fast or else.
The only way to recognize the problems and learn how to deal with them is to start with soil/soiless first to get that experience.
In hydro, a problem will hurt a plant faster than a newbie is able to research and try to correct said problem.
Aero is like hydro times ten in terms of speed of problems.

BTW Hydro does not suck it is actually a very efficient way to grow if you know what your doing....
Like said before the benefit of hydro is you know EXACTLY what ur plants are recieving and your able to also give them EXACTLY what they need if you have the right tools...
Hydro in my opinion is so much more efficient then soil if you know what your doing....
Oh,...and other obvious benefits of hydro are much faster growth, more bud sites, healthier plants, and more bud production just to name a few more...

I saw this problem..
I saw this problem..
same exact system in a 2x4 tray w 1gal pots filled w hydroton. the problem when flooding a table with freshly planted seed or clones is that the root structure is just not there yet and the overflow valve would have to be so high you would need a bigger res to get the solution high enough to even reach the roots.
Yes barricade is great ph up when you need to adjust a few tenths. I wouldnt overdo it. it is pure potassium silicate and can be toxic if used in excess. + if you use too much it will form into a solid chunk of silica slime. its pretty gross! I think top watering 3-4x every day with nothing but a root stim like voodoo juice or roots excellerator and b-vits until roots are present down low enough to start flooding the table w a nutrient solution. without roots its tough to uptake from the roots, so a light foliar of b-vits and epsom salts or cal-mg, kelp, w some form of humic will really jumpstart em into the vegative stage.
PS: B'cuzz is the biggest hoax on the planet. the root and bloom formula are identical, because their nothin but sea kelp!!! at $100 a gallon, a sucker is born every day. However, sea kelp is so good for plants, and I have used their stuff w success before I started to read NPK's and guaranteed analysis of what I'm tossing in res..

thanks for the observations. i will be care to to overfeed. do you think the dried up soil was responsible. maybe its different in e&f?
