Yellow leaves don't always mean over fert thats a huge missconception. It entirely depends on the way in which the leaves are yellowing. The ENTIRE leaf slowly turned yellow, it didn't have a harsh burn at the tip and move down. Also... because of the presence of red stems its impossible for there to be over fert.

All i know is that they appear to be doing great. Too be honest, it might not have been a double shot. I went braindead as i was making the solution and tried to remember exactly what i did and assumed it was a double shot it easily could have been a normal one. I know that sounds really dumb but its the reality of how I do things LOL :stoned:
