It could be a few different things, what media are you growing in? Could be too much water (don't really think so), too many nutes, or to few nutes, or even a PH problem.
Growing in FoxFarm Ocean Forest soil. The plant was started in Coco Coir. We has been watering with distilled water and then FoxFarm Tiger Bloom (6 tsp/gallon) every other time. I'm getting calibration solutions today so I should be able to verify PH tonight.
 
OK, first problem, Tiger Bloom is not used until week 5, and then at a 2 tsp/gal rate, so you're over fertilizing your plant with bloom nutes, when you should be using veg nutes (Grow Big) or a higher nitrogen nute, at 2 weeks you can add big bloom (not tiger bloom) use according to the FF feeding schedule for soil.
