Can a low pH spike doom a plant?

So like an idiot I added too much phosphorus into the reservoir last night and the acidity dropped very low (the indicator fluid isn't too accurate but it was very low). I quickly tried to correct it and about 40 mins later it was measured at about 6. Today the pH is still around 6 but she is drooping a bit, while she still looks okay I mentioned it to a friend and he said that he did the same thing to a few different plants, and each time they got worse and worse and then died... I've emptied the res and filled it back up with pH 6 water and am just letting it run for a few hours, but I'm wondering if I have doomed her like this or if there's any chance she'll recover?

She's in an nft tray and shes about a month old with 4-5 nodes
Her temperature is about 22C and humidity is 38%.
The EC in the tank is .6
other than what I think is a small Zinc deficiency (yellowing in between veins) and her current droopiness all has gone well.
Sorry there aren't pictures!

Any help would be greatly appreciated as she is my first and I'm quite attached!!!

IDK but good luck . I would like to think it will recover, but I killed one when my pH meter broke, but I didn't catch it as soon as you.

I'd imagine she is probably in shock. Whether it's from the wild pH fluctuations and associated lockout or from phosphorus toxicity I do not know, but I'd think you did the right thing changing out your reservoir. I may have even given her a one day water only flush, but I'm on my first hydro grow (always been a soil grower) so I'm not sure.

I accidently poured 4.5 PH nute solution on mine a few days ago. I just mixed another batch up at 6.8 PH, and flushed it with that. Plant was drooping just a little when I first did it, but she seems to be fine now.

Thank's for your input guys it's appreciated! Been letting her clean out and she hasn't got any worse so I'm hoping as long as I don't give her any more stress she'll be all right!
