soil/nut question...

ive noticed that when watering, the runoff always was orange, my soil is about 50 days old, when watering now, there is no orange color, does that mean the soil is low on nutrients?

Not necessarily, what kind of soil is it?

If it has supported 50 days of growth and you haven't fed anything it might be time anyways. The plants will let you know.

ahight, its 50/50 miracle gro/top soil. was thinking about getting the black gold coco formula soil. anyone ever try this http://www.altgarden.com/store/cart.php?m=product_detail&p=852.i have in a coffe can right now, shes about 16 inches tall.thinking about a 2-3 gallon pot.
