Most my leaves are getting these tiny brown spots on leaves. Not sure it's nute burn, light or pests. I am reading that using distilled/ro needs calmag but thought there be enough in nutes I am running.

Here is my setup:

Strain: Bag Seed
Age: Aprox 24 days from germ.
Light: (2) 26watt CFL per plant 6500k about 2 inches away
nutes: flora micro and flora bloom - 1/2 to 3/4 strength at moment (22ml/5 gals micro and 32ml/5 gals bloom)
Water: RO water every change <20ppm and Ph at 5.8 steady.
Temp: 77F in closet.
Vent: 4" fan in and 4" sucking out.

Here is the pics:
