Should I be worried?

I have a two week old seedsman northern lights auto seedling that's showing some stress.

I planted her in fox farm happy frog mixed with 30% perlite, 20% worm castings, and a few hands full of hydroton since a had a bit on hand. I dug out a hole, about the size of a fist, filled it with worm castings and put the sprouted seed in. It's been growing great until yesterday I saw some yellowing on its tips.

I'm wondering if the roots have grown out of the castings and into the happy frog soil and it's a but hot for it?

I'm watering with plain well water from my own well. No chlorine. I haven't been ph'ing since happy frog is supposed to be ph stable but my ph comes in around 7.5 out of my well, so it's not wildly off.

She's growing under a led that's about 24" away with temps around 78-80 and RH around 50-55%.

What do you think?

My advice: water around the perimeter of the soil rather than directly around the plant.

If you can dim the LED that might help. If the FF soil is indeed too hot, you can try to lower the rate of transpiration. You could lower temp, increase humidity, dim the light. Hopefully as the plant grows it will be more able to handle the soil.

There is a theory about the moisture level of the soil and the availiablilty of nutrients. I think it is that if the soil is more dry- the nutrients seem stronger. So if you keep the soil slightly moister, you could seemingly lower the hotness.

Lastly, if the soil is too hot you could give it a couple flushes, this would wash away some of the nutrients out of the soil.

Thank you, I can't dim the light but I could raise it. Perhaps a humidity dome? Noted on the watering.. I was watering close up since I have it in such a big pot (being it is an auto) and I didn't want to over saturate the big pot and push out all of the oxygen!

Yes, it is in a big pot but from what I've read, autos don't like being transplanted and they should be started in their final pot... so, I went with the big pot. I've been careful to not overwater.. using a 35ml syringe to measure small amounts to it, rather than just dumping.

Your precise watering methods are a good idea, but beware, the volume of soil you have is so large that there will be some dry pockets if not watered properly. The dry pockets may never recover and then there will be problems.

Make sure to do a full throughout watering every once and a while to make sure there are no dry pockets. One way is to bottom water and let the soil soak up the water from the bottom.
