Little spots on my little cheese?

[thisisearl]

It's day 68 on my little cheese; 3 gal soil perlite fox farm ocean, for nuts I give it the trio big bloom tiger bloom grow big compost tea between feelings along with occasional preventative foliar spraying; Epsom during early weeks. Got it under the 600 watt HPS right now Water ph 7.0-7.3. Runoff 6.3.Maybe these pics can better explain, any advice and possible course of action would be so appreciated

If its at day 68 I wouldn't worry to much. I mean in a few more days its going to start sucking the leaves dry any ways and you will probably be starting your final rinse.
