That picture is one for the plant abuse section. Here's my take, short and sweet:

1. Listen to Weezard and TPJ. Make them comfy.

2. Get a bag of Fox Farm Ocean Forest. Transplant immediately removing any old soil possible without damaging roots. Easy does it. 10 - 14 days in FFOF with straight pHed water. You can use an aquarium meter kit but note it will not be accurate when you add nutes due to discoloration of water. There is a work around for that too. No nutes or feeding until week 2 or 3 of flower.

3. Remember, the damage will never heal. Look to new growth to determine success. Also remember that any changes to environment, root zone or feeding takes 3 - 5 days to be expressed with the plant.

4. Leave it alone between watering (every 3-5 days in veg, a bit more in flower). Use the extra time to read up. The stickies here are good enough. See GanjaDigger for a very nice subject specific search engine that can help as you research. 420mag also has a very respectable FAQ section.
