    i have 15 white widow seedlings that are 4 weeks old and they are under a flourescent light for now some are about 6 inches tall and others are as low as 2 inches.  they have there first set of leaves and above those they have a bunch of good looking leaves that are multiplying each day. the only problem is that the bottom first set of leaves are all yellow they started out yellow on the edges and then turned all yellow slowly and they are slightly shriveled up.. now the top ones are getting yellow on the edges and im not sure what is causing this and what i can do to prevent this and also is this life threatening to my plants someone please help me if you know the answer to my problem should i put them under hydroponics even at 6/7 inches or what

    if you mean the small round leaves that came out first then you have no problem. The plant uses those as food to survive for the first couple weeks


    If you mean the first set of "real" leaves then the previous advice for feeding is prolly correct.


    What do you mean by "Should I put them under hydroponice even at 6/7 inches?" Did you mean High Pressure Sodium? (HPS) If so I put my babies under HPS when they are just a few inches tall.
