Looks like its time for nutes. Those "leaves" (if you really want to classify them as leaves) are where the plant gets its nutrients at first. They always die off sooner or later.
Fairly small compared to what theyll turn into. I transplanted my plants and im growing in soil and 2 days later my root system had covered a container 4-6 times as big as what they were in.
bwah, so 3/4 show the symptom, the cheese is doing alright, so i will see if it spreads past the sprouting leaves, if it does im giving em nutes, if not i'll wait till the end of the week!
