so, these plants (7 of them, 1 sativa, 6 indica) were propagated outdoors, in soil, under fairly poor lighting conditions (about 6 hours daily). once about 4" tall a couple were transplanted into a large pot with miracle gro soil and treated w/transplant solution, the rest are still in small nursery pots waiting to be planted and are inside amongst the planted ones indoors. light is provided by two 100w, daylight, coil style halogen lights & one 60 watt soft pink bulb, lights are kept 4-5" above plant canopy, kept on 24/7 until flowering. also is a humidifier (air is kept at 60%), & air intake & outtake (temp is kept at 80-82 deg. Fahrenheit) . anyways, after that time the plants (even the ones still in pots) had a vigorous growth that lasted about 1 week, gaining another 3 inches, bringing them to 7 inches. after that the growth stopped and a light dose of 5-1-1 fish fertilizer was added to encourage more vegatative growth. soon after one or two leaves began to show signs of chlorophyll loss, one leaf began to curl upward at the margins, two small leaves have been tipped white, and 6 of 7 stems are turning purple on the upper stem and petioles. what is going on here? im thinking phosphorous or magnesium deficiency? or maybe nutrient lock? was the fish fertilizer used too soon with the miracle gro soil already having fert. in it? (the soil used was new) anyways, here are some pics of said problem.
