I think I messed up my GH
 

Why do you want to keep such soft water ?
Plants do well in hard water as well.
I maintain healthy planted tank with hard water.
GH 12
KH 10
I do add CO2 and plants do just fine!

Thank you all for your responses. I can't tell you how helpful they
were. It's 11:13 in nyc right now and I have just finished replanting
my tank after i removed that evil gravel. It certainly wasn't easy -
i've been working for hours. I really really hope the gh goes back to
what it was coming out of my tap water. I can only imagine how
terribly stressful this has been to the plants and have little
confidence they'll bounce back.

Currently all the equipment is running and i figure i'll take a water
reading tomorrow night and post the params. If tomorrow night I should
find gh has not wandered back to the 3dh range should I just chuck all
the flourite (which still has some gravel embedded in it) and rebuild
the tank? I guess this is a bit premature...

Thank you all for your responses. I'll let you all know what goes down
(or up).

All,

I've just taken my water params again and all is well! After taking
out all the gravel and leaving only the flourite as the only substrate
my GH has gone down from a 10dh to 3dh (one dh harder than my tap
water). Thank you all for the assuring advice.

I agree.

Just keep an eye on it, and a KH of 2 is perfectly fine. But, the
normal nitrification process in the tank can lower the KH.

KH of 2 is a little closer to reaching that "crash point" than a KH of
3. And a KH of 3 is a little closer than a KH of 4.....

But, returning to the original query, he's setting up a planted tank.
With a KH as low as 2, the pH will have to be kept below 6.8 to provide
enough CO2 for good plant growth, or so goes the received wisdom, e.g.

which may not be a problem at all, but something to keep in mind.
