Seedlings in too hot soil, what are my options?

[teerull]

Ok ICMAG, i need you now more than ever. I cannot imagine for what possible reason I did this, but I apparently germed my seeds in soil that seems to be way too hot for the young ones. Containers are 0.2l "party cups", the really small ones. Currently under 50W CFL.

Growth is stunted, the little leaf material there is mostly twisted and curly with weird discoloration. I will get an image tomorrow as the lights go on.

I am questioning between pH issues or too hot soil but I'm pretty sure pH issues couldn't do so much damage so early. Just in case I gave them plenty of ~6.8pH water today and threw away what dripped through.

Here's a pic of them at day 4 doing super fine... Problems started soon after.

What are my options when indeed I'm dealing with a too hot soil? Transplant? Won't that seriously mess them up at this fragile age? Are they doomed?


Note to self: Stick to one brand of soil when it works

they dont look too bad. add some more soil for support . plain or low fert water.

You're fine using out of the bag soil unless its some really HOT stuff... I use canna terra soil which is EC 2.0 and my seedlings are fine...

 

[teerull]

Here's a few pics as of today. Day 13 since the first one broke the soil, the rest came after 2-3days. They had like the first 3-4 nights where temps dropped down to 14'C (~57F), since then temps have been between 17-26'C (62-78F)

You can clearly see that they are not doing well at all. (they actually look better on pics than they are really imo)

thanks for any input! Appreciated!
peace,
T

Don't transplant them!!! You hurt them even more IMO...Make sure not to over water them...but the way I see it...seedlings are like babies...in fact they are babies...very vulnerable at that young age...There could be a number of factors...the way I see it..every time seedlings get a little sick the first thing that comes to the mind of most growers is that the soil is too hot...I have seen seedlings started in miracle grow and still turn out to big strong healthy plants...It is easy to assume it is the soil...growers always blame the soil...

Hot soil can cause few problems for seedlings but not near as many problems as most growers like to assume..

The temps should be raised back up.....57 degrees is way too cool for them...they need a little more heat than that...and again...Make sure they are not over watered...if the soil did contain nutes in it, then by all means don't add any more...I see growers starting their plants in heavily fertilized soil and still adding nutes within the first few weeks....IDIOTS are what I call them..plain IDIOTS..but hey at least the nutrient companies love them..lol..

Let them grow a little more...and they will be fine...don't fuck up your grow based on an assumption that the soil may be too hot though...I am willing to bet the bank that it is probably some other factor that you might have overlooked...they will survive though...and the myth that Hot soil stunts the growth of plants is total Bullshit...it may stunt their beginning growth but that will not effect them in their adult hood...which means it won't affect the end product...post some more pics...and keep us all updated...

peace..

too cold, I agree with that... plus over-watered.

how good is the ventilation? I think they need more light too...

good luck!

Plants grow in the soil - the soil is the only thing to blame lol

Transplanting at seedling doesn't matter if your good at it, i start in rockwool then put into bigger rockwool that's a transplant, then 2 weeks later transplant into 2 gallons promix. Never seen any problems alot of growers use this method as well including breeders.

People aren't idiots for following nutrient instructions either - every bottle says to apply small amounts at seedling stage. With experience you learn not to add anything until the plant asks for it.

Back to the point - If you think your soil is too hot it's your gut feeling always go with you gut. Try to flush it out and give it a week and see what happens their young that they don't need much. If your really worried about it go pick yourself up a bag of promix or any potting soil and transplant it into something new and water it with RO give it a couple days it'll perk back up and fix itself once it's stopped being stunted.

 

[bombadil.360]

if the soil is too hot, flushing will only make it worst, as it will release more ferts into the roots...

carefully transplanting into a very low nute soil that drains well would be better than flushing... specially since the OP said he already flushed with pHed water...

good luck getting those ladies back into shape soon

peace

On a side note a buddy of mine had problems starting seedlings in white thin cups as well, he ended up with some root rot cause light was hitting the roots. Probably not an issue big something to put thought into. May wanna double cup them for better light protection.

 

[mexilandrace]

I don't know what that soil is, it looks like it has a ton of vermiculite though, that stuff holds water forever.

I think you should flush the shit out of them pour like a gallon of water through each one.

No matter what you do they are going to take a while to start growing again.

 

[ijimunot]

Are you using tap water?. If so are you letting the water sit in an open container and gas off the chlorine for a day or so before you PH it and use it. Chlorine is in the water to kill things including roots, beneficial fungi and bacteria.

Plants grow in the soil - the soil is the only thing to blame lol

Well, my friend all I can say to that is...keep thinking that...if that is what helps you to sleep at night then So Be It..lol...There are other factors that have an impact on plants. Air, temperature, light, water quality, watering duration etc.

Saying a comment like that is pure misinformation...

That's because the growers that do that don't have lives and need to create more shit to do...that is truly not necessary...too much transplanting...too much complexity...all I can say is...GET A LIFE...

People aren't idiots for following nutrient instructions either - every bottle says to apply small amounts at seedling stage. With experience you learn not to add anything until the plant asks for it.

IDIOTS!! Read my words...IDIOTS..LOL...Nutrient companies are in it to make money. They will tell growers anything in order to get them to spend more money.
In my opinion if one wants to fuck around with nutes and shit all the time then just go Hydro...the benefits are much greater...because you can obtain more yield...Why spend a ton of time reading nutrient instructions just to grow in soil?? Doesn't make sense...Soil growing is suppose to be more about taste anyways (which is another bullshit myth)..so it makes more sense to amend the nutrients into the soil...get a roots pruning pot that will create a dense roots system capable of utilizing all of the nutrients in the soil..and that's it....

The only difference between an experienced grower and a new grower is this...the new grower wants the nutrient companies and everyone else to think for him/her....the experienced grower on the other hand likes to do his/her own thinking....THINK MAN, THINK!!!!

Back to the point - If you think your soil is too hot it's your gut feeling always go with you gut.

Bullshit!!!

Try to flush it out and give it a week and see what happens their young that they don't need much.

Flushing with soil that is filled with nutrients will burn them even more..lol...quit spreading misinformation...If you knew what you were talking about then you would know that much..lol

If your really worried about it go pick yourself up a bag of promix or any potting soil and transplant it into something new and water it with RO give it a couple days it'll perk back up and fix itself once it's stopped being stunted.

He will further stunt their growth and damage them...it's not like they will die just because the soil is too hot...but fucking with them at such a young age will do more harm than good...

P.S. Damn! LoL, with advice like yours...no wonder why there is so much misinformation on these forums....

Are you using tap water?. If so are you letting the water sit in an open container and gas off the chlorine for a day or so before you PH it and use it. Chlorine is in the water to kill things including roots, beneficial fungi and bacteria.

Adding H202 will also help remove chlorine faster and kill any bacteria that have found their way into the water while it was in its 24 hour waiting period...

I was thinking the same thing...TOO MUCH VERMICULITE!!!...I wouldn't use that shit at all...water more often if you have to....that way it is more difficult to over water which is the main problem for all growers..

But if they are already over watered then flushing them is not a good Idea...a gallon of water?? with that much vermiculite?? Are you crazy?? That would probably kill them...

Besides...watering more frequently helps control salt build up...

once they are over watered you can't over water them more, he needs to flush out the nutes.

pretty much nothing you said was right.

 

[baan]

If I was in your shoes, I would flush with a ton of water and then add h2o2 for oxygen to the roots. But then again I sometimes learn things the hard way.

From the looks of it, a transplant would do more good than harm...

 

[stlsoldier531]

Can't over water them more?? And you say nothing that I said was right?? Hahahahaha....

So your answer is to drown them with more water even after they are over watered and the soil is filled with vermiculite?? Get the fuck out of here...LOL... are you serious...yo that's bad advice....

1.) In some fertilized soils...more water will release more nutrients and burn them even more

2.) there is too much vermiculite..it is already going to take a while for that soil to dry out as is...and you say run a gallon of water through there?? With seedlings that size?? BULLSHIT!!!

That soil will remain way too damp for too long...he would risk root rot by doing that...

 

[hazy]

yeah, don't flush. they'll damp off for sure. let it dry out a bit.
over watering in soil can leach nutes and cause deficiencies.
too cold temps for seedlings can cause this too.

 

[fredDRO.MoBB]

I would recommend to re plant in less hot soil like foxfarms happy frog.. I transplanted once in hot soil and burned the crap outta seedling. soon as I re planted in happy frog within 2 days the new growth was little healthier writhing week later she was back to normal. I know some people say it will stress it but for some reason mine didn't and i event took the dirt of roots well not all dirt but most of it.. I'll post a video on YouTube or Instagram follow me greenthumb_fredro. I'll plant a seed in hot soil on purpose and then fix the problem because am sure people finna say something about my reply

 

[DocTim420]

LOL...7 year old thread comes alive. No offense intended, but I bet the OP is not having this problem today.
