tomato seedlings leaves turing yellow
My seedlings seem to be growing very slow. I did move them into 3" jiffy pots when they where about 2 inches tall.
now it seems they have slowed down their growth and the leaves (seed leaves) are turning yellow.
I check the web some people said it could be from over watering. I held back the watering and still yellow leaves. Some have began to fall off.
I am now thinking it is a deficiency in the soil. ( when I replanted them in jiffy pots I just used the seed starting soil). do you think this could be it?
I have the plants in direct sunlight on the window sill do you think they are getting too hot? the house is around 70-76 during the day and drops to 70 or 68 at night.
Thanks in advance.
