Maybe slight ph fluctuations. Doesn't appear too bad though. Do you correct ph on your water before using it?

In the third picture your plant looks over watered and is probably the cause of the symptoms you're seeing with the other plant!

When growing in soil, you need to water with a wet/dry cycle! Meaning once you water don't again until about 2/3 of the pot mixture has dried out.

I haven't checked the ph, because i have been waiting for it to ship in. I made the mistake of being cheap and ordering from china with free shipping Thanks for the help btw! i think you are right about ph fluctuations.

Ok thanks i have been watering that one abit to much now that i think of it.

That's cool

I would not worry to much about pH as your using soil and it will buffer the water naturally, plus once your nutes are mixed most brands are in the acceptable ph range for soil although it is handy to have a pH tester!
