How would you fix: Plant in too "hot" soil?

[SmokinErb]

Title sums it up. I attempted to recycle so old soil, and amended it a bit too hot. I just transplanted vegging plants into 2 gallon containers a few days ago.

Could I pull the plant out, shake off excess dirt that the roots haven't thoroughly penetrated yet, and add some coco?

Soil mix is identical to Phillthy's. 1 bale of promix HP + EWC + FFOF + NSPB mix. Used it for one grow, then re-amended with more NSPB.

Got a brick of coir laying around, figure I could add 25% coir to the hot soil and then put it back in the 2 gallon bag.

I doubt flushing it would help, probably have to carefully transplant them.

 

[SmokinErb]

Okay, now since we're talking about an organic soil mixture here...

Is there anything special I need to do to coco? I know when using it as a hydroponic medium, you have to balance the pH, etc. Just hydrate it and mix? or?

 

[Full Of Peace]

to mix into your existing soil or by itself?

 

[SmokinErb]

To mix into my existing soil. What I'm thinking is that since I only JUST transplanted less than a week ago:

1 - Pull the plant out and give the root ball a good shake. This should remove a lot of the"hot" soil

2 - Mix the soil I shook of with about 25% coco

3 - Re pot.



I guess my biggest concern is whether or not its too much stress for the plants.

 

[Full Of Peace]

sounds good. most coco will work fine right out of the bag, if it's really cheap stuff it might be a good idea to run some water through it to flush it out some.
the coco will make it drain a little quicker too.

I've done exactly this but I cut the original soil fifty fifty with mix of sphagnum peat and rice hulls, the plants thrived after.


It would be more stressful for the plants to stay as is, don't shake the root ball too crazy though

 

[SmokinErb]

I went ahead and transplanted again. I used the rest of my seed starting mix, which wasn't that much. But since one plant was worse than the other what I did was:

Pulled out the Blue cheese, shook off the root ball. 3/4 of the soil came off with one quick shake, and I left it at that. Dumped the rest of my seed starting mix on the loose soil, and mixed well. I repotted her into the same grow bag she came out of.

I then took the remaining mixed soil and put it to the side, pulled out the Fruity Chronic Juice and a good shake also took off 3/4 of the soil. I then used all of the mixed soil and filled the pot, and threw a few handfuls of full strength soil that I shook off to fill it up to the right level, mixed it up real good in the bag and transplanted. Filled sides with full strength because that's all that was left.

I think it'll be okay. A nice reduction in nute strength to the one that's suffering the most, and a more mild reduction for the one that's just now showing symptoms.

I'll add some coco coir to the remaining soil before transplanting to 5 gallon containers for flowering.

Thanks a lot for all your help!

cool

If you search the boards you'll find one thing in common with the blood meal recipes...they burn......often.

Next time,(if there is one)take half the existing mix and half peat then mix together...make sure you lime the peat with dolomite or oyster shell powder at 1 cup per cubic foot of peat...or 2 tablespoons per gallon of peat. Add drainage/aeration amendments such as perlite or pumice to the peat.
Mix,wet,let it break down for 4 weeks before planting in preferably...but the 'cut' should make it usable now.

This will save you^^^


In case you haven't heard...try this method:

I recently had to do the same thing. Lost a week or so to transplant shock....much better than watching the ladies just die. Be patient...they'll come back around.

 

[Full Of Peace]

If you can get some Rhizotonic or other root inoculant it would help with transplant stress.

Hey there Smokin -

FWIW - there is VERY LITTLE blood meal in that mix....not nearly enough to burn, when used as suggested. Any left over N from a recycled round is likely from long-term break down of Seabird Guano and the soybean hulls that the dry molasses is sprayed on...

I like to use coir / peat at even 1:1 ratios when I mix a neutral batch of medium. However, this is only advisable when there is adequate soil / EWC to balance that out. I know you have seen my base soil mix posted before.

When I recycle the soil that I have used previously...I tend to use it like so:

2 gal unfertilized organic soil + 6 gal recycled mix
3g peat
3g coir
6g chunky perlite
2g EWC
1 bag NSPB: FLF

This ensures that I will not be burning my plants with too heavy of a mix after and I can effectively use another full bag of NSPB: FLF mix without worrying about any burn.

When using Phillthy's variation - on the second round you can simply re-use the recycled medium in place of the bag of FFOF:

1/2 bale Prom Mix Bx
10-11 gallons recycled medium (essentially 1.5 cu ft of medium)
3g EWC
5g chunky perlite
1 bag NSPB: FLF


Hope this helps you out in future runs...

I have also simply used the recycled medium over immediately for another round of seedlings / vegging plants, and then come flower they are put into a freshly mixed batch of medium...fwiw.

I've had soil with a little bit of blood meal make it hot for seedlings. Wasn't a lot of blood meal, but now I leave it out. Easy enough to get nutes to the plants with top dressing and tea.

 

[SmokinErb]

Thanks a lot for the input frank! I wasn't really sure how to amend, so I just winged it. I'll be mixing in an entire brick of coco with my unused soil before transplanting into flowering.

Transplant went well, no shock whatsoever. The next day I could already notice more growth. I cut off the bottom two affected leaves, but now, the lowest leaf on each plant again is showing some of the same signs. Starting to wonder if its not nute burn. The tips were curling down before, but no burning on the tips

Looks more like cal def to me, but I'm not the most experienced with these things. Brown rust-like spots appearing on the leaves.

Here's a couple of pictures that show the symptoms, one of each plant:

Watch em for a few days before you do anything else so you can know if its the transplant and improved soil mix that helped (or not).

I like to pair a compost tea watering at transplants, especially with sick/underdeveloped plants, help kickstart the new soil and the roots.

medium look really dry....imo - have you tried simply keeping things a bit more moist? I know when my plants get dry in a heavy organic mix, they tend to burn easier...

Frank - It's got to be the lighting. That was taken 24 hours after a very through soaking. Just checked on them a few minutes ago, and they're not anywhere near ready to be watered again. At least another 2-3 days.

The surface does dry a lot quicker than normal due to my ultra low humidity (20-30% with a humidifier running). The surface is bone dry right now, but not even a 1/2" down its pretty moist.

Will definitely keep that in mind though and be sure to water them about a day before I normally would.

Oddly enough, the one that doesn't have leaf tips turning down, was the one hit hardest by the nute burn, so I cut her soil more than the other plant, which looked mostly healthy before the transplant. Now the one that I cut the soil more - her leaf tips are no longer turning down. Looks like *hopefully* I fixed the problem with that one. The other one didn't get her soil cut as much because she looked healthier before the transplant, and so her leaf tips are turning down. Looks like I should have cut it a bit more. Don't think I'll do anything about it until I move 'em into 5 gallon containers though, unless I see some pretty serious effects over the next few days.

 

[SmokinErb]

Well just a quick update. They're looking much better. Only wish I kept better track of how much I cut the soil. Guessing 25% on Blue Cheese and 15% on Fruity Chron.

Topped the main leaders for the 2nd time and gave 'em their first vegetation thinning. Leaf curl as vanished or reduced significantly depending on which one you're looking at.

 

[dank.frank]

Glad to hear you got it worked out, bro....looking forward to seeing more of your results!!
