Those do look a lot like my bulbs. In fact, I went ahead and turned my lights off for a quick second to go investigate..

(the reason they're emitting yellow light is because they're still in the process of warming up in the picture)

I don't know if you can make out the letters "HPS" but what it reads, is "HPS 250 Watt Made in Belgium"
The Grim Reefer Reviewed by The Grim Reefer on . Yikes! The bottom set of leaves are folding under and twisting! I've done some research on my problem but I can't seem to find any answer. I'm sure it's probably something simple, but anyway. -It's currently day 25. -I JUST used a small (1/4 strength) dose of ferts on it to see if it could help out - No signs of recovery yet. -Temp is kept at a steady 80 F. -There is plenty of ventilation as well as some c02 flow. -The PH is 6.4-6.8 The leaves are a dark green, the tips are now getting crispy and have been curling under slowly for over a week now.
