hi just could do with a little advice please

Yes you should, and no, not too many.

helllo mate my plants are 3 weeks old from cutting at 5 weeks and on 4 hours of and 20 on at mo just wonderded when do i change is it when i flower cheers mate

Change the light to twelve hours on, twelve off when you want to start budding....

If they are 3 weeks old it will be O.K...The bigger they are themore bud you will get.
As long as they look strong and have lots of good roots you will be O.K.

and the leaves at the bottom should i now start to cut some of as they look like it should

Can you put up a photo? You probably shouldn't cut many off yet.

give me me ten mins mate and i will try to up load some but am not the best with the computer

mate it would not work keeps telling me file is to big but its just one file so i dont know if you do please let me know cheers any how mate

If your pics are on your pc you should be able to right click on them, then click Edit, then Stretch, and reduce em accordingly. If its a really high quality pic reduce it to 50-70%. My phone is 3.2 mega pixel and if im just posting one pic ill reduce it 80%, if im posting 3 or 4 ill reduce em 40-50%. Good luck man, every grow is different and needs different guidelines, so if you need help we'll need info

Peace

i cant get the size down of the picture, where's the missis when you need her!!!

open with paint,click image,click stretch&skew and resize to 30 or 40,thats what i do
