    Could someone please look at my plants and tell me what is the problem? Leaves are turning yellow and I dont know what else to do. I've cut off some of the yellow leaves. These pics dont show too well, but you get the idea. Organic soil. I've tried increasing Nitrogen. pH is a little on the high side but not much. 7-7.3 Growth is stunted. A month old, these are only about 6-7 inches high under constant 250w HPS. Water with Fish/SeaWeed Fert 2-3-1. And tried a 20-20-20 water fert also not with much success.
Somebody help me! I'm getting impatient, and frustrated! Need Bud!

    You think the 24/7 light might be too hard on them?? Was hoping the fan would strengthen them up, but that could be a bit much. But what's causing the yellowing with brown tip?? Impatient, I've begun to force-flower last night to try and sex these. Don't want to waste any more time!

I reckon Holistic is right about the over-fertilisation. It might also be over-watering. How often do you water and feed them? Also, how big are the pots. If you repot them in larger pots with good quality soil and stop feeding for a week or 10 days, they should take off. And turn the light back to 18/6. BTW, they don't look too bad. Some plants just grow a bit slower than others.

    Yes, I think Holi was correct about the over fert AND the fan. Watering every 2-3 days as the fan was drying them out quickly. Although I would wait until the plant began to slightly droop. I stopped the fan from ocillating & pointed it at the wall. A little strong, the fan may have been stressing out plants. The soil is rich & I was feeding with every water. BTW, they're sitting in 9 inch pots, pulled back on the ferts, and changed lighting to 18/6 as opposed to 24/0. Think Holi was right about that also. Still have some yellow leaves and more with a few yellow spots, but plants are growing taller already, standing up straight and leaves are no longer drooping. Just wish I could get rid of that yellow. I also tried to lower the pH a hair with lemon juice as suggested. That may have had a positive effect. Worked quickly.
Thanks for the Advice All. It's appreciated.

    
    
* 2-7-2004: Problem solved. Thanks everyone for your suggestions. I pulled back on the nuts in watering. Forgot that I set up soil with added nuts. Took the fan directly off them ( a little hard, and poss stressful). Raised the light higher off them to about 20 inches above the tallest, and changed the light schedule from 24hrs, to a 12/12. Changed the nuts in water to Miracle Grow Flowering and they look marvelous!
They are now large enough to try & sex. A foot and taller. I'll try to get some pics uploaded soon.
