Little spots just appeared

Yesterday was feeding day and I didn't notice the spots. They are only on one plant. The other one is fine. We thought it might be a nute lock out so we started a flush. We're about 4 gallons into flushing a 3 gallon plant. Runoff PH seems to be increasing slightly with each gallon of flush. Stopped to post while the R/O machine catches up.

E-indoor
E-soil
E-specific medium (not sure what you mean)
CSL-Soil type/brand Miracle Grow

SCL-Anything you have added to the soil Nothing.
SCLR-Soil runoff pH Less than 6.2 (that's as low as my test strips go)
E-Water source R/O Machine
E-Source water pH 7.0 (according to same test strips as above)

E-Age of plant Day 38 of flower
E-Type of fertilizer Botanicare Pro Bloom for Soil, Sweet, Molassas
E-Rate of application Bloom = 30ml per gallon, Sweet = 20ml per gallon, Molassas = 1 tiny dallop
E-Lighting source and distance from plant 21 1600lumen CFL's, 1 inch from tallest cola, about 5 inches from rest of plant & 2 4-foot flouros on the sides, touching plants
E-Air temperature Day 82 to 83, Night 77 to 78

E-Air % Relative humidity 40%
E-Lighting schedule 12/12
E-Type of ventilation your room has Passive Intake / 4 inch Vortex into Carnonair filter with oscillating fan inside tent (HomeboxS)

The pH of RO water means little to nothing.
You MUST be running CalMag on RO water and you have a distinct- guess what!- Ca and Mg deficiency.
Flush at pH 7.0-7.5 until the runoff reads 6.7 then feed with a solution of RO, CalMag, and half strength base fert at pH 6.7-7.0.

Thanks. I'll try to round some up right away.
