Ok cool, thanks, I'll keep it as it is.

Since putting the new lights in, the plant has perked up and bit and growing significantly better.

Just out of interest, when the plant reaches its 5th/6th node should the stem continue straight up and the nodal leaves grow at 90degrees to the stem? at the 6th node my stem seems to grow left, then the next node grows our right as if the stem is splitting....(picture attached due to shoddy explanation)

is this normal......Am i just being a paranoid newbie?
