o man i dont know what to do

[huh]

this is my first grow and im about a mounth into veg and one of my babies leafs are starting to turn dark brown allmost black on the lower fan leafs its like splatter marks and two days after i noticed that, they are staring to tinge a grayish color and get real brittle. im using happy frog soil earth juice nute and keeping ph at 6.8 with airerated water.

The leaf is dying and this could a number of many different things causing the problem. Could you give us more information such as how often you water, how often and how much you feed, what kind of lights are you're using, and how close are they to the plants. Maybe you splashed some fertilizer on the leaves?

What kind of water are you using? What's the average temperature in your grow room? Is the air circulation good.

If the pH is 6.8, then that shouldn't be your problem. What kind of pH meter do you use?
