should i revert back??

So after my first night of 12/12, when checking on my plants I found that they had some sort of deficiency (still working that out) and leaves were dying.... so today they have perked up a bit.... but my question is..


should i revert back to 19/5 for a week and let them recover, then try 12/12 again?


this is my first indoor.... and im sure ive read about complications going 12/12 and that some times its best to revert back to veg, then start over.

1 night of 12/12 wont take much reverting,
and it's best to sort out any problems first.
