Marijuana Plants in NEEED of HELP

I have a clone from the club growing in a pot in my backyard thats about 2 months old. It was growing really well until recently some of the leaves started to weather up and turn yellow. The plant as a whole doesnt look as healthy anymore and i havent really changed anything about it (but adding some rose/ shrub blooming nutrient about 2 weeks ago). Its also starting to lean and not standing up straight does anyone have any ideaaas???

are the leaves falling off from the bottom? if so thats normal if its that old is it still vegging or flowering yet?? if its starting to lean just put a stake in to hold it up...

its starting to flower but it still looks like it has quite awhile before it'll be at its full size

pictures help

well if its starting to flower then its normal for the leaves to start turning yellow and falling off. if the plant itself is falling over (im guessing because the stems are too weak to hold the buds?) just stake it and tie whatever branches you need to...
