New growth is always lighter Vs old anyway bud but kinda a lil hard to tell when it's lights off time just afore u shut it up take some pics with a normal light or flash it makes it easier to see the old hid lighting can make it difficult don't get me wrong easier than blurple LEDs but still proly a slight nitrogen deficiency if anything but need clearer pics to be sureSecond grown and having trouble trying pick the problem
Some on my bud site leafs are going a light green colour.
Rest leafs are nice green colour
