Mate they look smashing. It's only on the lower half apart from a couple fan leaves which never spread. I'm starting to think it's natural. Picking up cal mag anyway.
Thank you for the concern but no worries. All is going swimmingly.

CMH would be much better then that led you have. I have added one to my tent and plants seams to love it.   

Hi @bubbleguppie   The only way to increase yield is to veg your plants longer or keep a mum that's a heavy yielder, I really don't think you can push a plant past its genetic capability with bud boosters this and snake oil that.   There's no magic ways, it's all a con.   Best thing to do is make sure your environment is spot on and your plants have adequate light for what you wish to achieve.   I have the same size floorspace as yourself and to try and break my old personal best this time round I increased plant numbers. 9 plants in 3.5L pots instead of 4 in 6L. I figured I could pull an oz off each plant by rooting out the pots in 3 weeks and then flowering then I'd have a personal best of 9oz.   My attempt to break my record was altered by the fact I upgraded to LED and flowered with a much more efficient light compared to the 250w HPS I was using.   That doubled my personal best almost (250w which was 300w actual draw best yield was 8oz - the LED almost produced 15oz).
