Seedlings problem

So I've grown quite a few plants with great success. However my last 4 seedlings have got their first set of true leaves and then yellow up and curl down. I'm not sure what I'm doing wrong as I've done nothing different then I've done for so many other plants. It's really starting to piss me off lol.

Only thing I have changed is I went from FF ocean forest, which I hated, to promix. And 600w of CFLs to 600w HPS.

I just watered before pic, and I have not been over watering. I know it also looks like the drainage is bad but there is pearlite in the soil. I covered the top layer of soil with diamatacious earth. Could it be a bug problem? But I don't see any bugs. I'm super confused.

Looks like some type of heat stress to me EB. But not 100 percent sure. What are your temps like? Are you starting them under the full 600 watts? May be too much light at their young age.

Yes I am, but the 2 before these I started under CFLS and the same thing. My temp are pretty high let me switch back to cfls to see if that could be it.

Temp under cfls was high 70s , on hps high 80s, sometimes more

I've had this happen seemingly for no reason as well. I think in my case, I packed the cup too tightly with soil and the young roots choked. Ive also killed seedlings by letting the soil go dry; that can happen pretty suddenly.

It just seems wierd that it's happened 4 times in a row with 2 different strains. 2 at a time. When the first 2 died, I tried another strain and now their dying again

The soil itself has a certain amount of moisture within. I place germed seed into solo or pot and just let it be. It will " root " itself downward in search of moisture. The lower few inches provides a warm , lightly moistened area for this new baby root. It is extremely easy to kill the seeding by watering right off. I wait for germed seedling to " settle " in without doing anything for a couple days. Then I may lightly mist it only.

If these 2 die I will try that. I just don't remember me doing anything different with the countless other plants I've been successful with

This should help ... I just posted this with you in mind

It will work with most strains unless they are heavy feeders.
Just plant and let her go. Watering is done very lightly ( the key ) so the soaking entire container isn't necessary until plant is well established.

Dumped the plants and started over, did exactly what that link said and sounds like it could of been my problem. My past grows I've always watered soil until runoff then planted the germinated seed. This time im following your advice. I believe that the roots could of been choked from lack of aeration.

I also changed the soil to promix, happy frog, and more pearlite this time.

These last 4 plant failures had me really confused and on the verge of giving uo and taking a long break. So wish me luck with these 2 new plants under a new method.

This has caused you lockout,

I'd return to FFOF and add 30% perlite,

but for most FFOF is just fine

you need the perlite to resolve this

and a serious watering (3x the pot) allow to drain overnite in dim light

good luck
