My plants have had low ph levels by mistake

[Gooseboy]

My plants have had low ph levels of 3 by mistake. My ph pen was out. I have since sorted this. My plants are little yellow and slightly droopy. How long will it take to recover. Thanks any advice on how to recover my plants.

would flush asap 3 times the size of pot with phed water (if your in coco add few drops of nutes into flush water).

if you dont flush they might dryout and die.
made same mistake and lost few plants but the one thats been flushed 12 hours after the too low ph incident survived others did not.

and watch that ph, recalibrate ph pen,store it in storing solution,have another one as a backup and comparision, dip the ph pen into distilled water after done with ph adjusting found that it helps keep the ph measurements correct.
good luck
