seedlings not growing
I had started seeds for 3 or 4 years, always the same way and with the same equiptment.Then my life didn't allow me to do it for about three years. This winter I broke out all the old stuff and planted LOTS of seeds. I used the end of a 3+ year old bag of seed starter mix, and used the old light bulbs. I had no problem with germination. The new seedlings started to grow. Then they just have been hanging there, at varying heights, with almost no growth. For weeks.
The peppers stopped at first set of sprouting leaves, with the barest hint of a new set of true leaves. The black-eyed susans just barely got out of the dirt before stopping, the tomatoes put out one set of true leaves, etc etc.
The temperature is at about 60 degrees day time, and they have light for longer than it is light outside. I am watering correctly. The only thing I can think of is maybe the lights have lost some powere being old, or maybe the dirt was old. SO I bought new dirt and translanted a bunch to big containers in new seed starter.They did fine in transplanting, but have grown almost none again.
I have about 3 weeks to planting out, and I am extemely worried about why I'm not growing.
Should I change the light bulbs to new bulbs, extend the ampount of time the lights are one, fertilize them with a mild fertilizer? I figure the seed started has all that in it, it is Ferry Morse.
Yesterday I set them all out in the sun for about 2 hours, and will do the same each day it is nice and warm so they can get some real true sunlight.
Maybe I am forgetting something I used to do that is messing up the process. Does anyone have any ideas?
