Hi Hello Paul. Thanks for the quick reply.
The light setup consists of 1 dedicated fluorescent growing light + 2 cool white shop fluorescent. I measured the light with a light-meter and it was between 40.000 - 70.000 lux in different levels of the seedlings.
Like you said some of them looks really leggy but one reason might be that some of their bottom leaves got all yellow in the last 10 days, and fell down.
Soil is standart flower growing soil ordered online.
I was actually planning to plant them in bigger containers (the ones in the photos) and hopefully continue growing them indoors until the harvest.
I'm in Istanbul, so the winter is not really warm enough, but the temperature in the room is steady around 25-30 celsius.
They're growing kind of slow with strange leaf colors &shapes, so I was thinking maybe they could have some kind of disease, or I'm doing something wrong since I'm a beginner.
Any suggestion would be really helpful. Thanks again.
