Please help my girls may die young. Leaves yellowing and browning at tips. Only week 2 of seedling

[Greenmon23]

Sprouted 10/28, looked healthy for a week, and then this happened. Cant seem to figure out the problem. Using Coast of Main seeding soil and ILGM seeds. Using tap water with PH of roughly 6. Sf2000 spider farmer light 30in from tops of leaves. Was thinking it could be nut deficiency, but I didn't thinking seedlings had problems like this at only 2 weeks. Any and all advice would be helpful. Starting some new ones incase these end up dying, but want to make sure I dont make the same mistake.

Ok. Oh my ..... well. Ok don't panic.


Just repot those girls. And start giving em a bit to eat. They will darken up once they're eating and growing fast.

Should I stick with Coast of Maine potting soil, or switch to something else?

Lower your light to 18 inches. Don't do anything else for 2 or 3 days except possibly water.
That soil is Ok, but not living. You will either have to amend it or feed later on.

Soil if you want to amend and make a soil. ProMix HD if you just want to add powder or liquid foods. Those would be my pics.

Stay away from coco unless you go hydroponic.
It absorbs magnesium and your plants will need constant doses.

Not sure why one has a curved leaf. Could it be bad genetics?

Yep, but it's also somewhat normal. Plant leaves bud out in a 'ball' then expand to full size.

 

[Greenmon23]

So how would i go about amending the soil.

I'd say the soil is fine. You don't need to do anything soil wise. It's also way early to start feeding. Your high power flowering light is to strong for seedlings.
Nodes are very close together, light green, burned looking leaves. Can you dim the light? I'd say buy 50%. I start seedlings under 15w 6500 CFL bulbs.
Then bump the light level up after about 30 days.

 

[Greenmon23]

I thought it may be light but it was 30in and dimmed to 40%

I'd transplant, water properly (DON'T overwater) and at 2 weeks, you can begin feeding them.

Coast of Maine makes some great potting soils. If you have some of their soils for non-seedling plants, transplant them into that and don't feed for another couple of weeks.

it’s your watering practices, which are not too bad, i don’t see holes on the bottom sides of cups? is there holes in the bottom? if so put on something to allow airflow..

 

[Greenmon23]

Is this enough? Also watering daily when the soil is dry 1inch down.

I would repot, ive seen some say coast of maine was burning their plants at young age so maybe mix the coast of maine with happyfrog or something less potent. But i think if you repot up to aboit a 1.5 gallon pot, youll see better results, then repot 2 weeks or 3 weels later into a larger final pot. Thats what Ive done and it worked great.
Also do not over water the plant. Less is more when youre unsure of exactly how much water to give, so until you learn how your soil works with water, use less.

yep that’s good just put on something to allow airflow underneath.. when you think it’s time to water ( just in the next week or so), wait one more day than to water..

Yeah, you planted seedlings in a pretty "hot" mix for seedlings. As everyone else said, no panic...Just repot your girls let the roots spread a few days and begin a nutrient program 2 x weekly. (With plants this young I do NOT use a full dose nutrient but only one half as strong). These are not that bad at all. No worries.
Warmly,
Jackie
