I thought that might be the problem as they haven't been fertilized much; after reading about the interaction between cl/ca and mg. I know our water is hard. Never knew it would lock out other nutes. Thank you for your reply.
I was wondering if I could get some opinions? These are in Vortex potting soil under 250mh. Temp runs 80 with the light on, 77 with it off. Fertilizer Hasta Gro, and water ph 6.7-6.8. They've only been fertilized twice. Using light doses 1/4 strength. My original thought is a mg deficiency. They...

"You can't use a standard hps bulb in a mh fixture, but you can use a mh bulb in a hps fixture of the same wattage. I didn't think this was possible till several years ago when someone I trust told me it was possible. So I decided to try using a 400 watt mh bulb in a 400 watt hps fixture."...

So going off the chart the plant actually uses more blue light energy? Are their certain times during the plants life that it will use one color more than the other. Why do many recommend using hps for flowering if, according to the chart, a daylight mh would be better. Is there something else...
I wanted to throw out some thoughts that have been running around in my head... I found this http://futuregarden.com/lighting/PAR_chart.jpg . I'm using a 250w mh; seems this spectrum of light does nothing. Going by this it seems it would be best to go with a daylight mh. Thoughts? BTW light is...
