about to start flowering, advice please

So I have a few questions....

So I have a plant thats about 30 inches tall, .... the tips of all the leaves are yellowish, brown, dead, but the rest of the leaf is a nice green, the plant seems health otherwise.
I'm throwing it into flowering in a day or two. Any advice?

Is it true that a green light bulb will not hurt a plant in its dark cycle?

---Temperature:
Is 82 degreez when the light is on an ok temp? What if it gets up to 85 degreez?
-Should I use a small swamp cooler to lower the temp? Does this cause problems with humidity levels?

Hi 37,

can i see a picture..

30 inches is huge... What kind of light are you using? Brown tips and super dark green leaves usually mean over FEEDING... to much fertilizer...

are you pH ing your water?

cheers

I wish I had a digital camera....


What is ph-ing your water? I thought I saw that you can buy some stuff that you use in a watering cycle and it will balance the pH, but won't go too far.... ??
