What temps is he running though? LEDs need to be run warmer and I struggle to run HPS at 60-65f ( 15 -18C).Have a look at grand master levels latest series on YouTube mate. Hes experimenting with higher ph with the leds to get rid of the purpling in his stems, he's been feeding aat 6.7 I reckon instead of 6.3, and then every water only day he puts it in at 6.3 so it gets a drift. Pretty interesting really.
Does he run in run soil? 6.7 sounds pretty normal?
