Well first transplant that thing into a new pot with some good fresh quality soil and if you ph your water or nutes to 6.2-6.8 BEFORE YOU WATER YOUR PLANT you should end up with a lot less troubles than you have going right now.

A good quality soil will buffer your ph, keep your roots, happy, give your plant needed nutrients and make your job a LOT easier!!
Weedhound Reviewed by Weedhound on . I know it's not like limbo, pH too low? Why do you always meet us only when there's a problem? Yes, first post... Halp Please? I have a youngin' in soil and orchid moss (2/3 potting mix, 1/3 perlite, some? moss) and I think I've got a low-pH problem. I've got a couple days pH measurements 1. Feed @ 6.8; Runoff @ 5.2 2. 1/2 Feed @ 7.0, 1/2 Distilled @ 8.2; Runoff @ 5.0 Yikes! And a leaf discoloration with light edges and dark veins. Double yikes! Rating: 5
