Leaves turning yellow --------- help ------

I have two plants that are around 16 inch's tall, and the bottom
fan leaves are starting to yellow, I have just noticed as-well the tips's of the top leaves are a tiny bit brown? It's my first grow so a little worried about them, It is the First week of the 12/12hr, If any one has got any idea's on what it could be id greatly appreciate the help

Bottom fan leaves yellowing is normal ,
Slight tip burn points to slight over feeding,
what are you feeding them ?

pics and more infor for a more accurate answer m8

soil/hydro?
PH?
PPM (if hydro)
temps/humidity?
what have you fed them ?

also pics can say a thousand words man

Yeah picks....The slight browning on tips sounds like over fert esp. if it happened quickly. What r u feeding them? If its ur first grow u most be doing soil grow?

I was down in the local grow-shop and got a small bottle off
stuff of him he said it would do the job, For the yellowing on the plants
iv been feeding them advanced nutes, all so, what dose it
mean when the plants droop? mine seem to be doing that the now
and then, one day they are drooping the next standing up strong any ideas??

the Ph is 6.5, using all mix potting soil


here is a video i have on youtube that show's the prob, they are much taller than in the vid now http://youtu.be/fXU_smBCMx0

droopy leaves could be over watered.

Yellow leaves at the bottom is an indication that your plants aren't getting enough food. They will shut the bottom leaves down & send the sap up to newer growing points.
If the roots are damaged in any way, they will not be able to keep up with the plant's growth.
I would look at the conductivity and the pH of your nute water... something is not right! Conductivity of 2.0 - 2.5mS would work for a fast growing plant.
I have an article on this if you're interested. Not trying to sell shit here, just I've already written it so it might be useful... go to http://www.stumpykiwi.com/the-quality-of-your-water-is-important.html .

idk about you, but I'd rather wear latex gloves (without the powder coating) when trimming, so that instead of my hands getting black, the gloves do. THEN, I put them in the freezer and all that black stuff comes right off for some of the best finger hash.. And I'd rather smoke that, than try to absorb it through my skin with far less efficacy.

I know its a problem wearing gloves that don't breathe for a whole day, your hands end up wet, and wet all day isn't good. Wear some cloth gloves under the latex, it'll help keep you cool. Also you can run an air line from a fishtank pump to each cloth glove (tape to back of hand), and it'll effectively push all the damp air out and keep you dry all day.
