Humidity???

Im having some issues with my plants. I have checked my ph and moisture and nutes and all. Im thinking its either my plants are too close to the light source or my humidity is too low. My plants are about 4 inches away from a 150w hps. They are about a week old and have slowed down growing to almost a stop. The leaves are kinda folding up. Nothing turning brown though. They streched a bit due to poor lighting I believe but this light should do fine. The humidity right by the plants is at 35%. Is there something wrong here. Trying to save these ones.

I wouldnt say that your humidity is too low, however for vegitive growth its best to have your humidity around 50 - 60%. Then around 40% in flowering. Since you dont think its the nutes, ph, or moisture, Whats the temp of your room, all growth can come to a hault if your area is to hot. :fire:
 
I actually think the low humidity had alot to do with it, that and or the light being too close cause now the plants are un cuping and starting to grow again. hope that waas it but they seem to be doing alot better now that i added a humidifer to the room
