Help!! Brown marks on my leafs?

Okay i have no idea what it is or how to cure it?
My daily schedule with my two female big buds is 18 hours of light 4 inches away under 2 T8 fluorescent bulbs. I also water them 3 times a day, 8am, 2pm, and 8pm. The soil I use is Organic FoxFarm so the PH is controlled.
These two pictures are my plants at 10 days old, how can i cure this problem of the brown marks?

any1 please?

i have the same strain and its got the same problem :/

Looks like nute burn from the soil your using. Not a big deal though, the plant is still young so it probably has some excess nutes that it's not able to use due to how young it is.

The plant should recover just fine.
Just be sure your pHing your water. Even though the soil is pHed correctly if the water your using is not pHed then the soils pH is going to be thrown off.

Make sure you test the pH of the run-off when you water.

You need to back off on the waterings. 2-3 times a day is an awful lot. Wait to water until the top inch or 2 dries out.
