yes u shall transplant when seeing root at the bottom
that means u are root bound and the plant will stop growing and die

How i test if my plants need water, i put my finger in the soil..if its kind of moist then i let it stay their for a day, but if its dryish more...ill water it..thats just how i recommend =)

Good read, would under watering cause a slight yellowing of leaves?

the yellowing of the leaves could be from anything.........literally! my suggestion to you man is f'n read it all in........Order books from amazon.com about how to grow Indoors/outdoors, read it and then read it again, and again.......you will never go wrong.
this is my first grow as well and believe me at first it was very f'n intimidating but then i just studied bro and am still studying everyday as my babies grow.......i am growing under 3 x 4ft fluoresents (T-8's) from Lowes for $20.00 each.........and while i was there i bought a large bag of Scott's Soil w/ a N.P.K. of .07-.01-.03 for $13.00 and a bag of Miracle Gro perlite to mix in with it o that the soil can breath and allow the roots to breath which is the whole point............(i would not suggest usig any othr of he Miracle Gro products as they are difficult for the bewb to grow in asyou have to dilute it and all............get the soil and perlite and use tap water that has been sitting in room temp for 24 hours UNLIDDED to water your plants.......this is all your plant(s) will need for the first 2 to 3 weeks of their lives.....during this time the plants leaves will turn yellow as the N.P.K. begins to thin out from the soil mix from extensive watering for tyhe first two weeks of the plants lives..........after that .....well.........your just gonna have to go and buy some grub for your lil ones.......I suggest HTGSupply.com.......they have EVRYTHING you need and they i swear to the gods of all things green that they are a stand up ligit company...........see for yourself! good luck..........and P/M me if you have a Q that needs 2 b answered.

Yeah, if you underwater the leaves will wilt a bit and dry out, which will create some yellowing. But like jaedenn08 says, there's a lot things that can cause yellowing. Yellowing is like the plant's equivalent of a fever - all it says is that there's something wrong. It's how the plant is yellowing that's important.

If the top is yellowing more, that says one thing. If the bottom is yellowing more, that's a different thing. If the leaves are yellowing but the veins are still green, or if the yellowing is splotchy... you get the idea. Different symptoms spell out different issues.

can you post pictures on all the different types of stresses that you mentioned?

I have read in several places including the cannabis grow guide that you should have the plants in light for 24 hours a day during the first 4 weeks. Is this true? if not and I have had my new plants (really my first time trying to grow) on a 24 hour light supply for the last 2 weeks. Should I change this to a 18/6 or leave it as is as it has been this way for the last 2 weeks. I do not want to stress the plants as I have heard that this can happen when you change light cycle. (my luck I'd end up with all males!)

Thank you
