I'm a first time grower in need of some advice: About three weeks ago (2018-01-20), a repotted my chili seedlings into the pots seen in the pictures. Is it already time to repot them again? The reason I ask is because they are starting to look a bit tired: the leaves are becoming more pale green (some a bit yellowish), and some are curling upwards. I can also see roots poking out from underneath the pots. Also the growth seems to be slowing down.
It seems reasonable that the above symptoms are due to lack of nutrition (the pots are quite small, so theres not too much soil in there.) It should be noted that I have yet to water with any nutrition.
If anyone knowledgeable could give some input/confirmation, I would very much appreciate it!
