Seedling Advice

[Forest Bump]

Hey All!!!

Just looking for some advice. I'm 12 days in on my second grow and one of my plants started to turn slightly yellow around the edges:

I would like to identify what the issue may be before it gets any worse. All other 5 of my plants are doing great!

Soil: 50/50 mix of Happy Frog & Ocean Forest as the top layer and then Strawberry Fields below that.
Temp: 70-73 Degrees
RH: 50%
Light: 2 300w LED Light Panels, 2 ft distance from plants

Hopefully this is enough info. Any feedback is much appreciated!!!

When you've mixed different mediums, you really have no idea what to treat. OF is known to be hot for autos and will burn an seedling...usually from overwatering.

Thanks! I'll try lowering the watering frequency until the roots surpass the mixed layer at the top and never mix two mediums again.

Any input on what mediums you've had luck with?

Cool beans on your change...I've used bio bizz light mix for several years now...mostly because It's just easy...In the past, I've used ProMix, Humboldt soil, happy frog...I do prefer lightly nuted mediums......

Just started looking into bio biz. I'm intrigued. May explore that as an option. Again much appreciated!!!

I get this. The plants grow out of it by the 3rd node.
