    I have a few very small N. ampullaria and N. mirabilis seedlings.

    They have just passed the cotyledon stage and have thrown or started to throw their first true little leaf and pitcher (<2mm).

    However, they have slowly become quite pale over the last few days.

    The cotyledons emerged with that nice rich green colour so it's a bit of a surprise to see this colour change.

    Is it a sign of them not having enough (or too much) light? Or possibly something else?

    Aaron.

    These photos don't show the difference as dramatic as it is in person.

    The first is some N.ventricosa seedlings, You can see they are a nice rich green colour. The second is of one of the N. mirabils seedlings. It looks somewhat paler in real life.




    These photos were taken seconds apart, no change in settings and under the same light.

    Hi Aaron:

    It's part of the normal development of the seedling, they turn pale green or yellowish sometimes, but they are fine.......
    It's when they turn brown then you should really worry about.

    Thanks Gus,

    It had me worried but I was hoping my concern was over nothing.

    So I assume at some point the plant will swing back to a darker green colour as it matures.

    Also light levels can affect the colour of your plants. what light levels are you subjecting your seedlings to?

    Hi Aaron,

    have you tried to fertilize them? A very weak foliar feeding might help. I don't think the biggest seedling looks to well.

    Cheers Joachim
