I just planted 12 seeds and they all have grown about 3-5 inches but they have developed very small leaves none any larger than the size of a fingernail. But they are pretty tall and the stems are very thin. Is this normal and how long will it take for the plants to grow out the first big sets of leaves? It is the 6th day today of the grow and from what is have seen in pictures the plants should have more leaves and bigger leaves at this point in time. I have read posts about every week dropping the amount of light down 1 hour. Is this suggest or should i just keep them in the 24/0 until i want to make them flower?
