spots on leaves?

what is this.
happening on my mostly indicas Grape Inferno. not happening on my CBD or mostly sativas.
buds are not developing as fast as normal.
using super soil in 7 gal pots. in week5. pHd de chlorinated water, hygrozime, molassas, silica, weekly.
been treating with og biowars soil and BTI and green clean foliar for bug preventive, but still seeing some flyers. i think i had root aphids so the met 52 was added 2 weeks ago (thought the og biowars soil was preventative for RA?). not seing any larva on cut potatos on soil the last week.

i am thinking its over fert, i flushed one of the 4 yesterday, but spots got worse.
or these 4 got root damage from bugs worse than the others and are showing nut toxicity because roots cant uptake properly.

Mn or Mg where did it first occur where did it spread to?

Looks like a stress from spraying them in the lights on period.

i spray at 4pm and lights come on at 7pm
its only on the 4 Grape Infernos. the Accelerator and Sonic Screwdriver doesnt have these spots. all in the same room. temps are between 70 and 80. humid between 50-60 and co2 at 850.

started at end of week 4, on middle fan leaves
also seeing some clawing and edges curling (tacoing)

what about P toxicity?

local store said pH fluctuation
