Flush with a couple of gallons of properly ph'd water asap. NEVER give anything straight out of the bottle. Straight H2O2 for instance, will kill anything in the pot it comes in contact with. (roots included)

Perhaps this will be a great learning experience...
Next time...fill-out the troubleshooting form at the top of the Plant Problems forum, provide a picture if possible, and wait for assistance. When one posts a thread without all of the info, folks are less likely to try and help. Especially when there is not enough info provided to really help.
I'd start a new thread in the plant problems section, and fill-out the troubleshooting form. (copy and paste it into your thread)

Do yourself a favor...get ready for the new grow, (in case this one fails) have some patience...and read more. Lots more.

A far as nutes goes...Botanicare, Fox Farms, General Hydroponics all have solid nutes for soil. (I like the Fox Farms 3-part...great results) Check your local nursery or hydroponics dealer to see if they can order some for you.
