Hmmmm....could be a lot of things at this juncture. What's your pH in the cubes? What process did you use to ready the RW? What kind of lights are you using at this stage? How about heat / ventalation? These details might help diagnose....
sneekymofo Reviewed by sneekymofo on . My babies are 2 weeks old and starting to yellow! HELP! My plants are about two weeks old now and they are starting to yellow a little bit, and I also have one thats not acting like its wanting to grow very well. I was wanting to wait two more days before I put them in the Hydroponic system and started feeding them. They were doing great until I transfered them to the rockwool. Now as the new lwaves come in the have a bit of a yellow tint to them. Please check out the pics and let me know what do I need to do? Rating: 5
