Fan leaves spotting...??

My leaves are spotting in some places but all new growth seems to be healthy. I have 6 CFLs and 4, 4' TLs overhead so they should be getting sufficient light. If anyone knows what this might be let me know. 8 days into 12 12 cycle. Thanks!

That resembles K and/or Mg deficiency. What are your supplements, your ph, etc. It would be better if you fill out the form in the sticky.
