First Time Grower - Yellow Leaves

Hi everyone, first time grower trying only 4 seeds this time. I’m using Happy Frog soil, led full spectrum lighting. the room is at 70 degrees and RH around 65. the seedlings came up ok a week ago and have their first set of true leaves. the leaves are turning yellow on their edges. The moisture is fine and i originally had the lights 18" above but tried lowering them to 4" to see if that helps. Any ideas? I can post pics later if necessary.

We will need photos as soon as you can get them. Then we can help you out. :+1:

And welcome to the community.

Welcome to the neighborhood :grinning: The first couple leaves are sometimes wonky. What kind of light do u have?

Nothing expensive at this time. A 45w supposedly full spectrum with red blue and white leds

Under closer inspection it kinda looks white.

Looks over watered, how much are you giving them? A shot glass every 2-3 days is all that’s needed. Seedlings should be covered with a dome to create condensation for the leaves to absorb for around 10-12 days then I transplant at day 14 :love_you_gesture:

About that much. The moisture meter shows the soil on the edge of dry and moist.
Does that whiteness on the leaves look like mildew to you?

Starting to get further down the leaf.

No on the mold, Seedlings need a good amount of moisture in the air for the leaves to absorb. Are covering these with a clear dome like a clear solo cup? This will create condensation inside for the leaves to absorb. I keep a dome on the first 10-12 days and water around that dome :love_you_gesture:

I’ll try domes. They are getting worse the bent over one is just about dead. Is the light good enough or should I get a 100w led light? I never had these issues with tomatoes or anything else.

Give them 3 days between watering :love_you_gesture:

Ok I’ll try that. Right now they’re looking sad.

I spray the inside of the domes twice a day. I will also spray the outside of the dome where it meets the soil. No issues.

Thanks I’ll try that as well

Post mortem: All 4 seedlings died, never got past the second leaves. Tried everything but no luck. I have 2 more awaiting sprouting hopefully i have better luck with these.

I started 2 more seeds in a seedling starter and grew great transplanted to 5 gal. Pots and they grew great for 2 weeks now the leaves are turning yellow.
