I have put my small seedlings/sprouts in to my bubbler setup but they are not moving so much. Am I overwatering by putting a constant stream into the rockwool?? Should I leave the system off for a couple days until they grow a bit more so that they get some more oxygen and can handle the water flow in a few days/a week?
Am I Over Watering???

Just let the air do the work. Fill your water level up to the bottom of wherever your rockwool cube is. This will encourage downward root growth.

It takes a good week to get roots to start drinking from the bucket. What I do is top feed with just water until roots hit the water in the bucket. Just PH the water for now and get the water level as close as you can to the bottom of the net cup not submerging the net cup but very close to the bottom the bubbles splashing will give the roots the water they need and with in a week they will start drinking from the bucket and you should have roots in the water by then, by that time give them 1/4 strength nutes and start working your way up.

Stick your spaghetti line through the bucket using a drill and then into the net pot at lower end so water goes right below the rock wool cube. You can't over water in a dwc setup as long as you have enough oxygen being pumped in to it. What kind of air pump are you running? I am an air nut when it comes to dwc, I use too much which is always better then too little.
Also H202 will help add oxygen to the water if you are worried.

Too much water. rockwool should be moist but not soaked full of water.

You were helping me with this smae issue in my other post, thank you again.
how do you determine moist but not full of water? i know this is hard to describe. Im just down to my last 2 beans and wanted to have a 3 plant grow instead of 1. So Htey will be germed tomorrow and I have one more shot to get it right.
My Gro Dan rockwool is soaking in PH 6.1 ( i cant lower, I added 1 ML of PH down and it dropped the one liter bage of water to 3.1!)

If you squeeze the rockwool and water comes out..or too wet. You can't overwater dwc roots but you can rot your stem by having it sit I'm soaking wet rock wool.
If your ph down is too concentrated and makes adjustment difficult just dilute it with water. mine is dilute enough that I just pour it in my rez. Like a 1/4 changes the ph .1

I guess thats my problem, the rockwool has a top feed line pushin water at it nonstop. I'm down to 1 plant and it looks like it's not rooting at all after week. It hasnt broke through the RW yet anyways. How is it people use drippers and such but don't overwater? Seems like the RW would hold water for quite some time and even a drip would eventually saturate it.
Basically I don't need my top feed, I just need to go from germ to sprout in a container and then let it keep going until its roughly 2-3 inches tall them transplant the RW to the bottom 1/4 of my net pot and surround it with hydroton...Then from there just put my solution up to the bottom of the rockwool but not where it sits in it? So the roots have to reach for the water but the rockwool.

i'm haveing smae problem. i put my sprout in my dwc and top feed it until it rooted. it looked good for a week then wilted then it dried up . people keep saying i drowned it but that seems odd. i think i had a week air stone and i over used the nutes at first.

#1. 1000 ppm or even 800 seems really strong for such a small
Plant. I don't go 1000 until about week 3-4 of veg. Never over 1500 in flower.
#2. You may have some disease or virus such as damping off. This seems to plague beginners cause they are always touching and manipulating and generally never leave the plants alone when they are small and susceptible to such things. I would suggest a gentle flushing with some tap water and h2o2 to oxidize and bad things hanging on the roots.
Plants in mediums generally like to get wet, then dry out, then get wet. Too much water isn't the problem, it's too little oxygen. Soaked rockwool = too little oxygen.
