Newbie Needs Guidence/Pics

Hello all. First post, really new to this. got a few questions, looking for some feedback. Iv'e done plenty of reading on this site. Lots of great information. I am about 6 weeks into a closet grow(10x3x5). I started my grow with just a 250hps. I have added a 400hps on the other side and temps have increased about 10-15 degrees during the hotest point of the day running between 85-90(when the doors are closed). Humidity is between 35-55 percent. The tops of the plants are 10-12 inches from the lights. I got one fan. Have seen no signs of leaves burning. They do seem to get dry in about 48 hours and need watering. I've seen that the biggest mistake everyone says new growers make is overwatering. If the plants look ok, I am not overwatering right? I am using these self watering windowboxes for pots. I used plastic separaters to keep the plants apart. Anyone ever use these before? They were given to me, so I decided to use them. So far so good.

Looks nice. Doesn't seem to be any indication of overwatering. Keep doing what you're doing. I think you may need a bit more light, though for that big of a space. The plants aren't that big and some of the internode spacings are a bit short. At any rate, I'd say it's time to flower them! (IMHO)
