    IMO, cfl lites are not strong enuff to penatrate lower leaves. As long as top leaves are green and growing healthy, no problems. Maybe add lites to side when flowering. LOL

    when was the last time you transplanted....it looks like that potter is only about 1/2 the way full of dirt...I could be wrong...normally if your plants leaves are drooping and your leaves are dying/yellowing from the bottom up.....you need to transplant into a bigger potter

    You can pop your plants rootball out of the potter to take a look....if there are roots on the sides and bottom of the ball your will need to get a bigger potter

    One other item....your soil looking a the photo your soil doesnt look to have any perlite.......Might I suggest you get some good soil......the best soil I have found and been using for years in Sunsunshine professional growing mix # 4 http://www.ask.com/bar?q=sunshine+professional+mix+%23+4&page=1&qsrc=0&zoom=Days+of+%3CKW%3ESunshine%3C%2FKW%3E+for+US+Cities%7CWhat+Causes+%3CKW%3ESunshine%3C%2FKW%3E%7CYou+Are+My+%3CKW%3ESunshine%3C%2FKW%3E+Words&ab=1&u=http%3A%2F%2Fwww.sungro.com%2Fproducts_displayProProduct.php%3Fbrand_id%3D3%26product_id%3D139

    Yeild depends on the strain....lighting...soil... ferts used...how long in veg and how long in bud....how experienced you are...there are alot of factors that determine how much you can yeild off a plant
