Possible deficiency?

Just started my first hydro grow (RDWC)
Spotted a few strange shiny golden brown spots on one of my fan leaves and I’m not sure what they are. I’ve heard deficiencies progress fast in hydro, so I would like to catch them early. I also noticed that some of the new growing fan leaves are a little bit purple-ish at the base of the leaf. (Pics below)
RH: 45-50
Temps: 68-72F (although it does get as low as 65 on cold nights)
Water temps: 64-68F
PH: 5.8
EC: 425

Those nights temps are bit chilly but not terrible, to me they look a bit hungry. What lights are you using?
 
Okay good. I’m using two mars hydro sp-250

and when you say hungry, which element are you referring to? Nitrogen, Phosphorus, Potassium, etc.?
