5 day old cotyledon starting to yellow

[beckerjeremey29]

Help. My 5 day old seedling's cotyledon is turning yellow. I'm currently in FFHF soil. I give one squirt of water from a ml. syringe, once to twice a day depending on how dry the soil is. I'm using water phed to 6.0. The tent temperature is 80.1° and the RH fluctuates between 64% - 71%.
I think it could be overwatering, but I get nervous when they're this young. Especially when the soil gets dry. I already had one die, but the rest of them seem to be doing good with a similar watering routine, except for the one with the yellow cotyledon. I've also read that cotyledons yellow and die as the plant matures and no longer needs them, but this seems a little soon for them to be dying. What do you guys think? Do you think I should cut back on the frequency of my waterings to every day and a half to two days? TIA growmies.

less is more when they are babys. Make that taproot LOOK for moisture.

yea your over watering and ph is too low should be more 6.3 to 6.5

The cotyledons turn yellow as the plant consumes nutrients from them as it grows roots and leaves.

The cotyledons turn yellow as the plant consumes nutrients from them as it grows roots and leaves.

That early though? I remember mine always turning yellow in early veg.
