look in the pool supplies area for the ph up or down. That's where I've seen it.
Your plants should be able to be saved, just flush them a time or two to get the nutes out and let it go for a few days feeding it fresh water.
I think your plants are nice for 4 weeks. Don't give up yet!!

Flush them and don't give them nutes till they get better
