One plants struggles

[Skylinechili]

Hello Growers, on day 13 of my first ever grow. 9 out of 10 seeds had successful germination, 8 of the 9 are thriving, 1 is struggling. Indoor grow in self made grow box, 4 in 5 gal smart pots and 5 are in 3 gal smart pots. Custom blend medium of top soil, mushroom compost, crushed sea shell, Ash charcoal, worm castings, perlite. Medium PH of 6.5, only giving distilled water PH'ed down to 6.2. Light supplied by two 1000w LED's (320w draw each) and CFL for added blue spectrum. Environment with lights on is 76f. Humidity between 45-60, lights off drops to 62-65f. The sick plant is 1 of 5 Misty Cush strain. Any suggestions are appreciated. Cheers!

Hey Sky, nice ,young plants.
That sick one looks like she's been underwatered to me. Hard to tell from my end ,but sure looks underwatered ,
How have you been watering them ??

Big pots for seedlings could be watering habits.

I agree it looks like underwatered but medium still has decent moisture surrounding stem and root. I've been watering the plants in 3 gallon pots about every 3 days, 5 gallon every 4-5 days depending on how the soil feels.

One symptom I forgot to mention; my sickling is putting off a very strong marijuana scent. The others not at all. Not sure if that has any meaning but it's definitely unique to the unhealthy plant.

Hey sky, when mine are that size, I just give them about a half cup in a circle right around the stalk, a time or two a day, whenever it's dry, that way you don't suffocate them. Not saying you are, but that's how I do mine anyhow ,every body's different.
No need to water the whole pot when they are that size.

Don't think that is a symptom of any kind. You're 1000 watt is turned down to 320? Seedlings may enjoy a little more humidity. You can try cutting the top off of a water bottle mist the plant and place the bottle over it leave the top of the bottle cap off for fresh air. With such a big pot could be hard to get good watering practices down.

Thanks and I agree. I'm not able to visit them twice a day but I don't soak the pots when watering. I give just enough water to wet a ring around the plant. I check them daily to make sure it's not dried up. I was worried more about over watering!

I don't have experience but the other plants seem to love my process up to this point. I'm trying not to over complicate growing as it really isn't that difficult. My LED lights are full spectrum, 100x 10 watts each, the lights are pulling 320 watts from the wall each. Keeping them at a good distance since the plants are young, will lower as time progresses. 18/6 lighting, humidity does rise between 60-70% during lights off.

When lights are on plants transpire.Misting will help by drawing water from the leaves instead of the soil and help promote root growth. With lower humidity your soil will dry up faster. Not to mention fabric pots will dry faster as well. You're not that low but bell cloches are great for seedlings and a lot of people grow in humidity domes with seedlings. The other plants seem fine with what you're doing but sometimes different strains have different needs or need a little more tlc.
