Oh my friend , stop and think for a minute , to me your plants look good but in saying that I am new to this type of growing and problems that come with it , as was stated up close photos would help the guys here answer you problems , also check all the forums out there is a lot of awesome info from the guys here I have learn't a lot by reading them . It is up to you if you want to leave but you will be missing out on a lot of very helpful people and advice , If you stay I an sure you will enjoy AFN and be on a path to better grows , as we would say here in Auss -- steady mate .
