Odd Darkening of Leaves

[RakThatPunk]

• Hi Everyone! This is my first grow, you can see my grow log at AK-47 Lowryder Autos in Aerogarden - First Grow - Pictures included! In the past 1 1/2 weeks I have noticed the lowest leaves on my girl are beginning to darken

  

  I have started them on a low nutrient diet of at 130ppm as of last week. I just up'd it to 350ppm a few days ago. There is no signs of nutrient burn on any leaves other than these darker marks on the these three low leaves. Any thoughts on what this could be?

  

  It just doesn't seem like the typical burn that I have been seeing on the forums. Your help is appreciated!

What's the PH? It should be 5.5-6.0, thereabouts. This may be caused by a PH imbalance (too high or too low)?

Good luck

I noticed the PH level was around 6.2 at the time. I have lowered it and kept it between 5.5 and 6.0 for the past two days. I don't see any browning on the new leaves. Hopefully it was only a PH problem. I do see that the old leaves are still browning a bit. Should I leave the on there or cut them off? Any ideas?

Thanks for your help!
