Signs of trouble?

I have a 5 week old Bubba Kush in dwc (first hydro grow for me). It wasn't really doing much so I've bumped up nutes, now at full strength since last week. From what I've read, this looks like the very beginning of nitrogen deficiency but doesn't make sense because of the amount of nutes in there. One large fan on bottom left is turning pale/yellow compared to the rest. One small leaf on bottom right is yellowing with a burnt tip turned down. Do I have a problem in the making?
Humidity - 55%
Temp - 75 f
Water temp - 69-70 F
Gen Hydro Flora series & Hydroguard

Marijuana leaf ...definitely

My bubba kush is probably different then yours but it’s a slow grower in veg. Doesn’t need/like too much food. Takes off more in stretch and finishes hard.

No, I haven't been adding any mag (or cal) except for what's already in the flora trio nutes.

Worth a try,I add 60-80 ppm of Mg to my tap water.Or calmag if you have it,see if it improves.
