Temps in tent are getting too low.

How can I raise my temps? The leaves of my plants are turning purplish around the edges and yellow in the middle. I think it is a phosphorous deficiency do to the low temps. At night the temps drop to 59 degrees. With the light on it only gets to 70 degrees max.

My setup is in a 5x5x8 tent. I have a 1000w hps and two inline fans. Right now the exhaust fan is the only one running. If I push air in the tent through the bottom instead of exhausting it out of the top will the temperatures raise?

The overnight low sounds just about perfect if you ask me. The problem is the daytime temperature. It needs to be up between 77-81 degrees.

I would try switching you exhaust around like you suggested but if that doesnt work why not just put a heater in there on low?

Thanks for the responses. I can't support the wattage of a heater. I should have stated that in the original post.

I'm going to turn the exhaust fan off and put in on the bottom as an intake fan. I will get back with the results tomorrow.

My leaves are turning a bit yellow. Can I foliage feed them P and K or should I just add more to the weekly feedings?
