I'm having problems deciding if this is nute burn or not because I'm doing a fairly light feed, so far only happened to one plant, I looked for bugs because on the picture it looks like something been eating it, but I can't find any.

Barneys Farm LSD
Nutes are (in 10 liters/2.6 gallons) Canna Coco 15ml of A and B, 40ml of Rhizotonic, 25 ml Cannazym, PH 5.7
Temp 78f, RH 35
600w Osram nav-t super about 19 inches from the plants, been under this lamp since yesterday
Water is tap, no chlorine.

Sorry, no EC measurements.

Thanks
