Yellowing veins

thasme · #1 (**permalink**) 04-03-2009, 08:25 AM

I have 2 plants that are 5 weaks old along with 12 other seedlings that are 1-2 weeks old growing under a 400 watt HPS light 24 hrs on in a Soilless mix. I realize I should have the plants under a metal Halide but the HPS is what my electronic ballast order came with. The room 5x12 is goin to be recieving one more 400 watter with HPS, and than a seperated area 3'x5' with a 250 Metal Halide. Anyways the 2, 5 weakers are begining to get yellow veins, the leaves are a nice green color no yellow and the edges are not yellowing. The exact soil is the Miracle grow Moisture control with about 30% perlite added per pot. The Miracle grow contains some fertilizer and I have not began any fertilizer regimend as I have yet to order some. So my question is what fertilizer should I order (online) I am not worried about organics, and what am I defecient of currently? thanks

Sounds like the 5 weekers need fertilizer not the young ones though. Get Fox Farms or GH. Or just get some miricle grow since you like the soil.
