Well right before I repotted my plants the lower starter leaves turned yellow. I was hoping that repotting them would fix the issue (N deficiency?). Didn't spread for a day or two but now the next set of leaves are starting to turn yellow and the little starter leaves are turning brown on the tips.

I did add a little pure blend pro grow to the water today to see if it will take care of the possible lack of N. I also ran to the pet store and grabbed a PH test kit and tested the runoff of the watering, the kit shows the runoff being around ph of 7, and water before was around 6.2-6.6 so that means the soil itself is around 7.4-7.8? Which is in the 6-8 range so I don't think PH is the cause.
