I am a little unsure of how much to water tho, i usually fill up a .5L water bottle and split that between the 3 big plants, and maybe all of them, so i am not quite sure if i am over watering, or if it is just too many nutes at this stage.

Also was wondering when i should change to a 12/12 cycle. And if i were to guess i would say that this was a sativa plant as well from what i smoked of this weed before i planted the seeds. As for the lights, would anyone suggest using a lighting fixture that doesnt have the metal reflective sort of dome i have on mine? Or does this not matter much, if at all?

Alright, I'm going to do a bit of your work for you. However, you need to spend some serious time reading the FAQs on this site. All the questions you have asked have been answered many times over.

First, about your pH. Soil grows need to stay in the 6.3 ~ 6.8 pH range. At 7.0, your plant is complaining. You need a way to check the pH of your irrigation water (including any nutes and suppliments) and you need to be able to adjust it either up or down. There are commercial preparations available.

Second, about watering. You can depend on two things to help you decide when to water. One is your finger, the other is your arm. You stick your finger into the soil about an inch or two. If the soil is dry, then check the weight of the pot. Is it heavy or light? If heavy, then you probably shouldn't water. If light, water completely until you begin getting runoff from the drainage holes. Do not let your plant sit in this drained water indefinitely, get rid of it. When the plant is watered thoroughly, use your arm and pick it up. How heavy is it? Remember this. This is what your container and plant feels like when watered. Now, let plant dry out fully before watering again. Use your finger and arm as needed.

Third, you change to 12/12 light cycle when you want the plant to start blooming. You can only bloom mature plants (ie, a 2 week old seedling won't want to bloom).

Fourth, I can't help you on the CFL bulbs or reflectors as I don't use them.
