Yeah I have basically finished my grow box, I am growing in a barn (about 21*C in the day, 17*C at night, drafty so no ventilation trouble, 40% humidity, pH is 6.3, watering when first inch of soil is dry (about every 3 days), 16 days old, not on nutes yet as cotyledons are still there, 1 25w 2500k cfl, i know i need more lights, but is this the reason my plant is yellow, or is it some other reason? I am getting 6500k cfls very soon. Help is appreciated sorry about the squashed photos, not sure wat i can do.
PH to 6.8, lower the light until its about 2 inches of the top of the plant, and start a weak dose of nutes.. something like liquid seaweed would be a gentle start for her.. good luck
its 1/3 peat moss, 1/3 perlite and 1/3 vermiculite as of 2 days ago, before that it was just plain potting soil ( probably another reason), light is 2 inches away and i have recently put another light on it
