There is a definite issue here. The leaf growth looks a little wonky. I would bet its something with the PH of the water in question. If you are truly running a ph of 8.7 this is far too high for proper nutrient uptake. Try to get it down around 6-6.2 and monitor the ph of the run off to get an actual read of the soil PH itself as apposed to the watering PH.

Hello @clmbs ! I don't think there was a problem. If it was a problem the cotyledons would never become green again. Maybe you were late and you didn't put it under the light as soon as the seed popped . Happy growing ! 👊

Hi @clmbs! We’re missing some crucial informations here: what’s your medium? Do you have the NPK ratios for this substrate? Do you check the pH and EC of your waterings? If so what are the current values? How often do you water and how much (volume)? My guess is that you over-watered the roots, it’s a common mistake with small plants in big containers. As a result, plant cannot drink all of the water and roots are suffocating, they can’t get oxygen anymore. Roots need to be on a wet/dry cycle to properly spread, searching for water. Each cycle should be pretty quick (24~36h) so you should always water with 15-20% of the container’s capacity. Never water with more than 25% of you pot’s volume. Hope this will help, keep us up-to-date and happy growing 👊
