    Are the dying leaves the first two leaves to grow on the plant? If so, that's normal. They're called cotyledons, commonly known as seed leaves. Monocots have one leaf and dicots have two. If this is what's dying it's ok.

    If it's not the seed leaves that are dying it could be the fish emulsion burning the leaves.

    Are you watering evenly?

    Leaves turning yellow can indicate too much water. And if they are six inches tall they need a grow light, not a flourescent.

    They are probably deficient in something, fish emulsion is not going to provide everying, and if your growing medium contains no nutrients, like many seed starters do, they may need something else. Try some compost tea or something.

    I water my seedlings with a diluted solution of liquid seaweed. It helps the root system develop nice and strong. Fish emulsion is nitrogen, which on down the line will help the leaf growth of the plants.

    I have a couple flats of several vegetable types, including peppers, tomatoes, herbs, lettuce, etc. I only recently transplanted a few of the peppers to larger containers so they are about 2 inches tall. One of the pepper plant's seed leaves have turned slightly yellow on the tips. Also, a couple other pepper plants have actually shriveled, but are not yet dead. Would anyone be willing to tell me what/if supplements need to be added? They are set up underneath flourescent lights and are watered reliably without too much drying in between waterings.

    Thanks!

    how close are they to the lights? I find if I let the plants get TOO close that will damage them/

    They are all sitting about 2.5 to 3 inches from the lights. I don't think it's the lights, because so far, it is only the seed leaves that are yellowing. The effect isn't on everyone plant either. Only on a parsley, pepper, and flower start.

    don't the seed leaves always yellow and drop off?

    @ tikaani:

    What supplement would you recommend then if it is too much nitrogen?
