Clones rooted and transplanted but not growing

[dubnation]

Hi 420fam. So I took cuttings about 20 days ago. They all rooted in rockwool after about 8-10 days and then were placed in roots organic soil in solo cup. I've watered them twice since in soil and my most recent water was a few days ago. I used some coconut water, Kelp Meal tea and diluted with pH adjusted water. Out of 9 clones this one is just not responding well and leaves are beginning to curl.

Any advice on what I should do?

Other key facts:

RH in upper 60s
Temps around upper 70s to mid 80s
T5 HO lights are very close to clones (2-4 inches)

Thanks!!!

Just my experience, but clones in rw will stay too wet if you water directly on the rw cube.... when i use it i usually pull off as much of the rw as i can, damaging as few roots as possible at transplant...

Ah great idea. Yeah that was a big concern of mine that the rockwool stays too moist in the soil. So I try very hard to only water the edges of the cup but I know the RW will wick up all the moisture.

My plan has been and will continue to let the cups get super light before watering. It's 2 days since my last one. And usually 4-5 days in between watering.

Just did a Epsom salt foliar spray on them. Maybe it's MG deficiency?

When I used rock wool I pulled as much off as I could too. You can still do that while it's in soil. Having too much water near the stem discourages roots from searching for water further away and also blocks oxygen.

Keep in mind that even though clones are genetically identical, differences in the cuttings will cause clones to develop differently. Some will develop perfect balance between roots and leaves, etc. Most are lacking in some respect. And inevitably some clones will root but take longer to establish balanced system and lag behind others.

Edit: I see your new post above and agree you are on right track. I would still try to remove as much rock wool as you can. Pulling slowly it usually separates around roots and often I can get all of it off.

Nervous to pull off the rockwool but will try. I assume since it's been in soil for 8 days that I can only get to the top of the rockwool.

Next time during transplant I'll definitely try that.

My buddy says the twisted leaves are from too much nutes already in the soil. Maybe the Kelp tea was a bad idea.

Will watch her for next day and see if she improves.

Thanks for the help!

Remember that nutes are for healthy actively growing plants that are actually using them. Plants that aren't growing aren't using nutes and don't need any more.

If she doesn't improve should I flush?

She doesn't look that bad. Flush would stress her more. Probably better off just waiting for her to turn around. If she does start to show more signs of nute burn you could try flushing, but I think unless she can do it herself you'd be better off letting her go. 7 out of 8 clones is a good success rate.

Thanks Kingston. I also subbed your latest journal too.

Here's something I'm noticing. The main stem has a brown color on its lower 3/4. Is that a sign of something?

could be bad roots/rot.

 

[KingstonRabbi]

Sorry, I think it's time to let her go. Root rot or stem necrosis.

 

[AngryBird]

yeah but just for the process of learning.....take a close look at the roots.. and the bottom of pot. Smell the soil.

 

[dubnation]

Thanks folks. It's unfortunate but not a total loss. I can grow the 5 White Russians that are doing well and try cloning the Chronic again. The soil was reused and contained some old roots from the boys that I chopped last month. I'll only use fresh soil for clones from here on out.

Are there drainage holes in your solo cups? Invest $1.57 for some reusable pots. They are designed for growing plants and will do a better job of keeping light off of the stems. Add more perlite to your soil mix. This will also help with drainage and allow your roots to navigate through your soil better. Defoliation will also help your plants soak up water and encourage root growth.

Yes there are drainage slits cut in the bottom of the solo cups. I used them for germination and 9 out of 10 did. But this is reused soil which I should have amended and added more perlite.

Turns out the issue was weak cuttings. The good cuttings I took rooted 4 out of 5 and are now in 1-gal pots with perlite and EWC along with fresh soil.

well it's a good one for clones 4 out of 5 Merry Christmas

 

[dubnation]

Here is the sole survivor from the weak cutting. I'm just letting her do her thing. Slowly growing two tops:

Behind her are the 4 of 5 transplanted to 1-gal and begun LST.

Dubnation I just read and dealt with some moss/mold issues myself. Molds, mosses and other living things like to grow in a ph of 5-6. If your soul isn't neutral (I'm suspecting it's not because of it being used.) you would be more likely to have root rot issues.
