Indoor Heat Stress?

[ashorama]

I checked on my seedling last night. It has been growing fine but I found it doubled over and the top of the seedling touching the soil. The leaves felt crispy and there are burnt edges on them.

It was under my 150-watt HPS light. The light is about 2 feet over the seedling, so I was thinking that was far enough away. I had plenty of in and out air. The only thing is that I didn't have was a fan going in the grow closet.

I watered the seedling, put a humidity dome over it, and faced 3 CFLs with reflector backs on it. I also started my fan. This morning, the plant is upright again, but the leaves are still very crispy.

What're the chances of this seedling recovering? It's Northern Lights autofem, which I understand is pretty resilient.

Any feedback would be appreciated.

Hey bud, sorry to hear of your troubles, seedlings are pretty resilient in general, I'm betting it'll be ok if there is still some tender growth. Is it just part of the leaves thats crispy? Pic would be good.

I just added two pics, @surffreak. Thanks for the feedback!

Yikes!
looks like it may be a ph/over nute problem, could we get some details like age, soil, nutes etc? Have you measured the ph at all? Being an auto it may be pretty stunted but if you correct the problem it should still survive to produce some bud.

I just checked the pH. It's in the low 6 range (closer to 7).

The seedling has been above ground for two weeks on Sunday.

Here's my soil mix (I got the recipe from this forum). However, I didn't put in the eggshells but put in 1.5 cups of earthworm castings.

25lb bag of compo
18Qt Bag perlite
3 cups of Blood and bone Meal
1.5 cups of powdered egg shells
1.5 Cups of Epsom salt
1/2 cup of sea weed kelp
1 cup of powdered baby cereal

The seedling got its first nute feeding last night. It was a combo 1/4 of a teaspoon of Dyna Bloom and 1/2 teaspoon of Dyna Grow.

I would hold off on any more nutes for now, looks like the soil may have turned out a bit hot for it. Just keep the ph at around 6.4 if you can. You could try a flush, but it only does so much in organic soil...

Thanks, @surffreak. Much appreciated.

I just transplanted the seedling to another pot. I took about half of the above-mentioned soil and put in the bottom of another pot. I put some Fox Farms Happy Frog soil. I mixed it a little but not much. I wanted the Happy Frog on top. I sprayed the seedling with spring water and put a humidity dome back on it. It's really up to the plant now. I started germing a new bean just to be on the safe side.

Thanks again for all of your help.

No problem bud!
Hope it shapes up for you soon! Sounds like a good remedy to me, hopefully it doesn't shock too bad (or at all) from transplant...

Just my two cents worth. Humidity domes are good until the seedlings pop. Then let the youngsters breath. Take the dome off as soon as they pop.

Adding CO2 is good idea when the heat gets up there in the grow area. I've been using The Green Pad CO2 Generator and my girls are loving it.
