brown and light green spots? please help!

my plant is 20 days old and the strain is northern lights. its vegging under 4 CFLs in fox farm ocean forrest soil. the nutes im using are FF grow big and big bloom. i've fed it twice so far, last time was 10/17 at half strength(i now know is too much). it was doing awesome until a few days ago. little yellow spots started to appear and now they are big brown spots and light green around it. one of the leaves it half dried out but its a light green color, not so much yellow.

does anyone know what this is?? please help me out because its getting worse.

What about your ph. Do some research on ph levels in the search engin, its a nice lookin plant.

looks like nute burn. i would flush with ph'd water and then go back with even less nutes like 25% to start. nice plant, she'll be ok they are very hardy plants!! good luck!

my ph is about 6.8. i've looked at ph fluctuations and i think the leaves would be droopy and curl downward. i dont have any curling, just wierd brown spots. im a total noob tho so i dont know haha. thanks man
