Hey Leprechaun....we's just messin with ya...the yellowing is probably either from overwatering...it's easier to do than you may think or a nutrient deficiency of some kind....very gently try giving them some nutrients for veggin (you can read up on this stuff here: http://boards.cannabis.com/grow-faqs...nutrients.html ) should be like a 16-8-8 or what ever, but higher in Nitrogen, maybe at 1/4 strength and wait a few days to see how they react. They don't look that bad, so don't think you've screwed them up bad or anything, but they may be gettin a little hungry. Also read up on watering and when to do it and when not to ( learn to pick up the pot and tell by weight when they need water) Ya might wanna learn a little about ph as well.

Also go here and download at least the grow bible and read and learn!
