Howdy Buckaroo,
I've been where you are, and I know that the info is out there saying to use lime, but there's better ways to cope with your issue, which simply is acidic soil.
If you subscribe to the school of thought that your soil is going to tend to take on the characteristics of what you put into it (like we say "you are what you eat"), then you can control your ph and prevent the problems. A good flush with warm water will stop things from getting worse, but dying leaves are going to continue to die, and there's a tipping point, where you plant is past the point of a viable harvest. You have no photos, so hard to say.
If you're using municipal water (aka tap water) my own informal observation is that it's usually quite alkali, mine is off the charts, and friends in other cities report the same. So you really need to control what the ph is in your water. Use warm water for your normal watering and allow for plenty of run-off and don't let it sit in its own water, if you use drip trays.
Your current grow may be fucked, I don't know, but applying this for the next time will improve your success.
Edit: Add perlite to your soil mix next time, allows for more drainage and makes regular flushing less stressful.
