Hey man they look good but they look like they're suffering from nutrient burn... What are you feeding them?

Do they have roots, whats the lighting like, what temps and humidity are you running? sorry man it's hard to give good advice with limited info...

Definitely looks like high nutrients. With Rockwool you should just dunk the cubes in 5.5 pH for 10 seconds. Then put the seed in 1/4" and put it in a zip lock or prop tray with a dome. They will be good for the first week.

Edit: obviously in a bag you would have to open it once it rooted

Do you have a ppm meter? Just because you didn't add nutrients doesn't mean there isn't a high amount in your water. My tap is about 300 which is a little high for seedlings

Ec and ppm are same. Just different measurements. So 1000 ppm is 1.0EC so if it's around 250ppm I guess that would be .25EC

Flush with distilled/boiled water. I test all my water before. My tap fluctuates from 7.0-8. It's easier to start with a base water and build up then correct.

Your ec for plain water should be under 0.6... pH should be 6.5
Your rockwool looks dry in some of the photos... it should be kept just barely damp at all times- the dome would help. You need more light too... go to a 100w output (usually 37w) bulb for that many seedlings...

We had this problem a lot with Rockwool-- it just doesn't seem to stay evenly moist... I would get them into party cups of seedstarter ASAP for a better chance-- unless you are going hydro???

For hydro, get a nursery tray, an airpump w/tubing and one of the long "stick" airstones..... lay the airstone down the center of the tray with the seedlings on each side of it right up against it.... fill the tray with enough water to cover the airstone and about 1/2 way up the rockwool...and turn on the pump... DWC hydro germinator!

No Dome- just leave them till you see roots... then get into your hydro system...

They are young sprouts, you can fix this.... ;)

I'm sorry but I heavily disagree. .6 is too high. Under 6.0 is where the pH should be. And you definitely don't need all that to germ for hydro. A simple soak of the rockwool for 10 second in 5.5 adjusted water, add seeds and put themunder the closed dome for 5-7 days under close 24hrs cfls or fluorescen . Save the air stones and pumps for your permanent sites

absolutely! I completely agree! also I would recommend waiting to transplant at all until you see root development :)

I was just going to transplant in to soil cant afford that for hydro what should i do i have a heated propagtor and my main grow room is a 400 w mh for veg n a 400w hps for flowering would i be able to gently remove them from the rock wool and place them in soil or keep it in the rock wool and could i place them under tht light or is it to strong
