Is this over or under water or something else

this is my second grow and seem to be havin more trouble this time round my little guys are turnin yellow and curling under i just cant tell if im under or over watering. im not soaking the cubes and im not letting them dry out WTF is goin on.
temp is around 23oC

Those are stretched quite a bit. You can start by getting the light closer as long as it will not become too hot there. Are you using Flouros for veg? If you are you can get them within a couple inches of the tops of the seedlings. They are stretching to try and get closer to the light. As far as the yellowing, it looks like over watering to me, but I use soil and am not familiar with working with the cubes.

the symptoms are the same for under and over watering it looks like the seedlings are ready to move into what ever your grow medium is

i was thinkin the same thing a min ago and just finished putting them in there clay balls. i water them once a day is that too much or too little.

Alright, so put your sprout in its new home, I dont know why you are transfering them into clay balls you should pot them. And you can get along watering her once every two days most likely and make sure to water around the stem not directly to.....dont want to get root rot

wat do you mean pot them, like a different substrate or actually into a pot because they are in a 4'' pot with clay balls now.

easygreen i think now they are in a new medium the roots will stretch out and everything will straighten out good growin..rob
