A couple of my Babies (3rd week) have weak stems

Are these two the unforunate victims of root rot? Is there any hope for either of them? If so what do I need to do?

They have both been pretty much running sideways (limp) since they sprouted from 1 in cubes (Germination from seeds on the 14th).

Watered once while under the clone dome (on the 20th), I'm thinking I didn't need to do that.

I would open the dome gradually....first starting for about 5 min a day starting around the , eventually leaving them uncovered half a day then eventually all day....all very gradual...perhaps too gradual.

Anyway, they are now in 3 in cubes as of Sunday. The other 6 seem to be doing very well.

Here are the pics and if you have questions or need me to elaborate, would be happy to provide whatever information I can.

DrG

Either my thread went too far down the chain, my issue is too difficult or I am freaking out over nothing. Regardless...

BUMP!

it looks like you dont have enough light what lights you using?

125w Sun Blaster CFL (8750 Lumens) at < 1ft away from when it was in the clone dome and is now roughly 2.5 to 3 ft away from the plant right now. Surrounding area is covered in flat white

lol it looks funny, that is odd... someone had this same problem on here. maybe its a mutant?! just kidding. i think your theory is as good as mine but, my advice is to put it into dirt and bury that elongated root. only let an inch of the plant stay above the surface And do you have a fan? indoor plants dont fair well without some kinda of resistance(wind), it forces them to become thicker and sturdier. but your plant looks like it sprouted only 3 days ago. i'm sure what has caused this but get the light closer. and re plant it if you want it to live. you left it in that incubater dome for too long, and with too much moister i think. root rot makes some sense lots of water in a very humid dome, the plant is trying to grow a long root, maybe the other roots are rotted below the surface. if i were you, i would cut the root off where it meets the dirt and re plant it.

Ok, so here is what I did:

Went over to the local floral shop and asked them for those plastic card holders that they stick in boquets and such....these are going to be my support sticks, so they're standing upright now. Secondly, I have mounted a small fan inside the box to move some air around. I set this to the lowest setting, the fan is targeted away from the plants, but the space is relativley small so I think they are going to get just enough airflow to move around a little bit.

I need to check on some of the others tomorrow....looks like I may be getting some leaf curl.

Fun, Fun stuff. I can't wait until they get a little bigger and resilient. Now I know what a soccer-mom feels like when their "little snowflake" gets sick.

man, if I saw that plant on the beach ibwould kick sand in his face lol. Anyways, your lights were way to far away. A cfl needs to be right next to them. Like 2-3 inches. The plants stretch to the light. Adding any kind of nitrogen in the young stage can also cause this. Once it gets a few more leaves you need to turn the fan ON them. High enough that they are moving from the air. This will slightly damage the stems and the plant will react by thickening them. Mj plants evolved outdoors where there is wind... Not in an airless vacumm.
Good luck, keep us posted

good call on the fan but the real problem is your rockwool cube. It simply holds too much water to be valuable for your plant. Try a hail cube or even a peat start. rockwool just doesnt cut it. Ive had that problem until i switched my starter plugs. after the plug stage i break the plug off and gently rinse the roots in room temp water and place them directly in my hydroton.

bring the light back to <1ft , 3ft distance is too far even for hid's

Agreed, 200%! You were doing it ass-backwards, man.lol 2-3' would've been fine for cloning, but is terrible for growing. Bring it down well under 1', as close as possible, without the heat burning them.

I'm putting in a third vote for lowering your light to stop that stretching. With a 150w HPS (no glass, integrated ballast) - I keep it about 6" away from the canopy with a small fan blowing across. A 125w CFL should be able to be placed even closer (esp. if they are under a dome which will block a lot of light as well).

Agree.........all of the above!

Okay, brought them closer to the light. Ran the fan on them and they seem to be doing much better (2 days later). I am noticing that one of the plants seems to be having a little upward curling and twisting the tips of a couple of leaves. I'm wondering if this is Nute Burn, Mg Deficency or a by-product of not having adaquate airflow prior to me installing the fan. Here is a pic:

Highlighted Area 1 is where I am seeing the upward curl.

Highlighted Area 2 is where I am seeing twisted/shriviled leaf tip.

its the light. CFLs can get SUPER close to the plants. with that much wattage try to have it about 5 inches above the plants. and if you see slight burning just move them a LITTLE higher. CFLs lose light rapidly when they are too high above the plant.
