Is this a nutrient burn/deficiency problem or is it a light burn problem? If its a deficiency I might just switch to chemical fertilisers, Iv had not much luck with organics. Any help appreciated.

EDIT: Could my water pH be too low at 6.2?

400w is about 12inches from the canopy with no fan..really low ambient temps here at the minute tho.
 
I looked again and stay with my first diagnoses of light burn as the leaves are fine. could it be spilled nutrients and just a stain on the leaves?

and I am remiss, what kind of soil are you using?

Biobizz All-Mix with extra perlite, just transplanted from small maybe 10cm pots to 10L pots.

EDIT: The roots had started circling on 5 plants when I was transplanting but I "agitated" them lightly...Id say I loosened up the root ball with my fingers as I was of the understanding this encourages them to grow more?
