Use sharp scissors. They are not effected by pruning much and are very
tough. Even the "stumps"
with no leaves will produce new leaves. Prune at will or as needed.
For propagating them..... emersed growth in a greenhouse or emersed
terrarium. I have grown A. hastifolia inside as a houseplant even. Place the
plants in small pots with soil, a little peat and some sand for drainage and
about a inch to three inches of old tank water and spray with a fertilizer
once twice a week or so. You can use other tabs and jobes etc but the sprays
seem to work the best.  You'll see they do grow quite fast then. 1 to 2
watts of FL light is plenty for them. Submersed, many grow them attached to
things but I think they do much better in the gravel.

Not at long winded! You just ripped up your tank and re- did it. A major
change. You should expect some "crashing". Adding new intense lights
I'd suggest doing less of the RO water............maybe not using any.......
depending on your tap water. Get your GH and KH up to 6 and 4 or so. Plants
can handle it just fine. Mine's 6KH and 9GH. Just use the CO2 to drive the
ph in a good range for your KH. You may have some adjustment using your new
higher powered(?) lights too. A new balance to achieve by adding more energy
to your tank............
TMG is great( I and many others use it) but in SF we find that adding some
extra K+ in the form of K2SO4 or KNO3 can certainly help lots. We add KNO3
when the NO3 levels are low and add K2SO4 when they aren't low. Your holes
**COULD** be from a lack of K+. Adding more wouldn't hurt. Check archives
and KRIB on this topic.
Adding the fast growing plants is a wise move and some patience will do the
rest. Keep upon things and wait for the tank to get "plant cycled". This is
different than simply "cycled" and it takes somewhat longer to get back on
line after there's been a big disturbance like removing a large sword plant,
adding a new lighting set up, moving a tank, etc......................

There are chemical cycles beyond the common bacterial "fish only" cycles
most of us are familiar with, that help plants do well and grow great. How
many times have APD'ers seen a tank doing poorly even though all the test
indicate all is well and on line but always after a major change of some
sort? Many times I have "tortoured" tanks too see how far I could go.
Point is: be patient and keep up on maintenance. It will get back to normal.
Try using Equilibrium by SeaChem for adding Ca and Mg etc...or add that tap
water or more a percentage of it. You can use whatever source for Ca.
Holes are a sign of a mobile nutrient I believe. Ca is not one.
OK I was right! 
It's likely to be K or Mg that's causing problems but I'd say it's the NEW
tank needing to re-establish itself more than a nutrient problem. Patience
FWIW, Regards,
