I run a flood and drain so this is only a theory......

I think H&S was right about the rock wool being too wet. How many roots have exited the wool? My guess is that since your plants are small, 80-90% of their current root system is still inside of that soggy rock wool.

If I am correct, stop watering the rock wool for a while. Do not let them get bone dry, however. If you have some roots exiting the rock wool, make sure they are getting water.

If I am right, this problem should fix itself over time. For now, you have shorties.

P.S. Next time either use 90% less rock wool (it is only there to hold your seed, so it can be tiny) or, even better, replace the rock wool with a tiny net cup filled with hydroton. I switched from rock wool to rocks years ago due to similar issues.

Best of luck to you.

Cheers

Thank you very much for the reply I will absolutely do that some of them have really long roots three times the length of the plant lol

So I went into the room and pulled the Rockwool out of the 4 healthiest that has the same issues of super close nodes to do a comparison of them next to the ones in rockwool to see if it corrects itself. I was gonna do them all like that but 4 plants in and lots of damage to roots later I started rethinking it lol I’ll give it two weeks see if there is improvement.

Do you just go from seed to collar?

Yes.

I currently go directly from seedling to collar. I germinate in a moist paper towel until they are 1.5" long or so, long enough to fit safely in a collar.

At that point they are still too small to put in my flood and drain. They would be too small for your DWC as well. The roots aren't long enough yet.

I take the tiny collared plant and sit it in damp perlite for a week or two (basically a tiny hempy) until the roots grow several inches long. Once the roots are long enough I gently spoon out the plant, rinse off the perlite, and drop the collared plant into my system.

I hate perlite as much as I hate rockwool but unlike rockwool, it's super hard to overwater and is reusable if you want. And for this use, you barely need much of it. (ProTip: wet perlite is way easier to work with than dry perlite)

I want to start using aeroponics for my clones. Does anyone have a suggestion on a particular system? Or a link on the best way to build one?

Excessive P will cause short plants with extremely close internodes. Some plants are most sensitive than others to P.

I have an Exotic Genetix plant that looks just like yours. The direct result of my dumbass watering a couple veg plants with my bloom (higher P) mix after grabbing the wrong jug.
