need some advice...

[swtjo]

I accidently overfilled my pool a bit and some of the overflow went into my garden. today the tips of the leaves are curling and drying out. also some leaves have a splotchy yellowing. this is happening on one plant but the other one next to it is fine.
I dont really know how much pool water got on it but I dont think it was more than a couple gallons maybe? (hopefully not more)
any suggestions on what i can do????
Thanks

hmm that stinks.. I am no expert but first thing that comes to mind is Ph of your medium, also maybe root rot?
