HELP!!! Is this mold???

I want to keep this short and sweet:

Ph 6.9
Medium-Fox Farm Ocean Forrest and Light Warrior mix
Light- 250 HPS Agro Max
Temps-75-84
Humidity-can range from 30-51% usually around 40 and below
Nutes-Grow Big so far, very little bit every other watering
This plant is 18 days old

There are weird little yellowish brown spots on this leaf that look like something ate away the top layer and replaced it with this yellowish brownish spot. I could not get a true color picture of this because it is dark and I was using my HPS as the background light. You can clearly see where the spots look recessed from the surface of the leaf. Please help and cast your opinions on what this is and how to fix it.

The second pic is just some sexing porn of what real deal Lowryder should be doing on day 18. Gotta love the doctor

doesnt look like mold to me m8 it seems that you may have a hungry pest somewhere about your grow by the way the top layer of the leaf is looking something seems to have skinned the top layer for a quick meal.mold will useually be a white fuzzy substance that grows where the light doesnt dirctly reach and in worse cases more widespread. causescan be temp probs like over hiumidity and over watering or a pest problem where pest waste actually grows mold i thonk you are safe from mld 4 now..

STANDOX- thanks for the help. I discovered what the culprit was- I use goGnat an organic Cedar Oil based pesticide to control the spread of fungus gnats. I had killed all the adults a few weeks ago and the remaining larva hatched last night causing a final spray of the goGnat. My atomizer has a leak at the handle and a few lone drops landed directly on the leaf, at 33.3% cedar oil and a few other acidic components you have the resulting spotting and burn. Talk about a case of the paranoid growing the paranoid, haha.

good job ....u got it on the money thanks for the tip
