I think it is possible.  I have seen similar responses.  I once had some
Ceratophyllum develop severe Ca deficiency with whitish leaves at the tips
falling off in four days, and it recovered with new growth in only one day
after I added some lime.  I have seen increases in pearling in less than a
half hour after adding nutrients.  We can digest food and get it in our
blood stream in 15 minutes or so.  Plants can also take up nutrients and
move them around quite rapidly.
