You probably don't need each layer to have a water stream and blocks under the water, just let the cactus bump against the glass and fall all the way down to the bottom. That said, there's no cactus where the hole is so you can break those panes around the hole; the cactus drops won't be positioned in such a way that they would ever be able to reach any of the cacti on the lower levels.
Removing all of the glass will help: all the glass at the intersections (diagonal from the columns with cacti) and enough planes so each cactus column will grow next to only one pane which (being unconnected) should be a 2x2 pixel rod.
(Only one side of the new cactus block need have a block to harvest it and the more open space for the cactus items to drop the better.)
Running connected glass panes top to bottom as suggested above will avoid losses to cactus items resting on edges and despawning, as well as to falling into cactus in other columns, but will increase losses from the cactus items 'bouncing back' into the parent blocks.
Building the farm Space|Space|Cactus|Pane|Cactus|Space|Space will also lower the losses due to falling on/against cactus blocks making the farm more efficient on a per cactus basis, but will increase the footprint for any given number of growing spots and so decrease efficiency on a per volume basis.
As mentioned, cactus farms generally use only one drop collecting floor (water or – more rarely – hoppers) beneath the bottom layer of plants; any increase in fratricidal losses as the items fall from the upper levels are offset by the ability to pack more levels into a given volume.
[Unless you are interested in maximizing a particular measure of efficiency as an end in itself, I suggest just building something that supplies a "goodly number" and not sweating the details.
This assumes that your only goal is a 'good' supply of cactus; if there are other considerations (ie. you like the look of a particular build), those factors will control.]

WARNING: I have an extemely "grindy" playstyle; YMMV — if this doesn't seem fun to you, mine what you can from it & bin the rest.
Personally I'm using fences instead of glass panes (yes I know Xisuma extensively tested and concluded that glass panes were the better option) and I'm having really high rates with a single layer 16x16 farm. However, if a farm this size doesn't give you the rates you're looking for, I advice you to build another layer on top with it's own collection waterstream, this will prevent second floor cacti falling on the cacti/fences/glass panes below.
If you really want to get the maximum rates on a minimal footprint check out Xisumavoids video on cactusfarms! ^^
I guess in the end it depends on what exactly you're saying. Are you saying the drops land on top the of the glass panes on the same floor of the cactus farm, or on the glass panes of a floor below? In the first situation I'd say go for fences since their hitboxes are higher, in the second I'd say build an extra collection waterstream between the different floors of your farm
You probably don't need each layer to have a water stream and blocks under the water, just let the cactus bump against the glass and fall all the way down to the bottom. That said, there's no cactus where the hole is so you can break those panes around the hole; the cactus drops won't be positioned in such a way that they would ever be able to reach any of the cacti on the lower levels.
Cactus drops are getting stuck on the glass panes in my cactus farm when they fall down to the collection point.
Is there a way to fix this or is it just a part of the loss of the farm? Does it need those glass panes or can I break them?
I believe it was suggested in another thread that one make it glass panes all the way down.
That way there would be no edges for things to get caught on.
Just testing.
