Purple punch single plant

These were taken today. Checked my calendar and realised there 2 weeks further into flower than I thought, due to this they have abit of nute burn on the blades and i havnt added any pk yet (maybe why the buds are still a bit small, maybe theyll fill out who knows), but backed off the a+b today and should be off it in a few days.... and added the pk in hope it'll take effect still Another week/week and half to give the pk chance and it'll be flush time I Gone without rhiztonic this grow not by choice but again just forgot as I wasn't expecting this 1 to come to anything
