@Budwizer, I think you're wrong mate. My leaves are green, stems are green. my plant looks nothing like the google images of a nitrogen deficiency. I'll watch it, just in case something happens.
@cheese420, I did some more reading up on the mainlining technique, you have to top at the 3rd node, but last night when I checked, topping at #3 would leave a moerse hole in the stem coz it's gone nice and thick, so I topped at #5 instead. Once the new tops are established, I'll chop everything below and start the LST.
