Good timing before your update then.
Did you try yourself to harvest hemp/hemp fiber and linseed/flax family ? I had a look to the crops files before productions for balancing and i see things like only 3000 liters/ha for fibers. In the spinnery, flax-fiber fabric recipe ask for 288.000 l/month so or I didn't see a big "factor" when harvesting or there is a problem.
IMO the problem is more than lower the input. I'd say only 0.3 litersperSqm isn't enough for fibers EDITED, see at the end.
After that, the ratio 24 fibers for 1 fabric isn't easy to understand, 4 to 1 would be more "credible". Lets say you have 8000 l/Ha of fibers, 2560€ in direct sale, with a 4->1 recipe you have 2000 liters of fabric, 8000€ value. It seems too much but actually your Onion crop give 8500€/Ha without the need of a factory (sugarcane give more so nothing weird ;) )
And finally your recipe gives 12000 l/month, more fabric than the vanilla cotton (7500) where cotton has a 4* liter price comparing to your fiber (0.32 -> 1.252) so for a global game balance fibers should produce less pallets than cotton (only 1.5 for wool), between 4000 and 5000 l/month should be ok, 16k to 20k €/month isn't a scandal and if you want to produce it all the year long you need between 24 and 30 Ha (51 for cotton) so you probably wont do that all the time.
All that for only 1 recipe :D (and for basics game prices per liter of course). I give you the 1st list I made yesterday with your culture fruits (as many of your productions need theses ressources I need to be sure these are final volume/prices to have the right number for balancing prods. I.e. linseed oil price and recipe will depend of the liter/Ha and price/liter). So if in your vision of the gameplay you want to change some values, tell me.

EDIT: I made a quick try and I understand that you split Lin into 2 plants, 1 for seeds only and an another crop for fibers only where this one (as hemp) don't use the: <harvest litersPerSqm="0.3" but only the windrow part. In vanilla game even grass use the "harvest" value that's why I was a bit lost . So it's not 3000 liters/Ha but 50.000... (11000€/Ha for hemp and 16000 for flax). Your recipe is still unbalanced (50% of the fibers value) but now if there is a problem with the litersperSqm it closer to "too much" than not enough.
Yes in a perfect world we'd have a machine between the cotton and patatoes one which would let the whole plant (flax) on the ground for few days before baling and drying/"brushing" to obtain the perfect fibers . but we're in a Giants game so very far away from reality ^^ and I don't think they bale hemp (not after having this sort of windrow ). So having the opportunity to have the mower in the front and the wagon to the rear to harvest in one passage is not so crazy.
The spinnery accept what WE want :D I know, vanilla spinery accept only bales and pallets but that's not so hard to add a trigger for bulk if you want (ok now you can't on mac OS). actually I added hemp and lin on a map I like where my spinnery produces twine/fabric with flax and rope/fabric with hemp, I just create a trigger and add in the xml
<unloadTrigger exactFillRootNode="exactFillRootNode" fillTypes="FLAX_WINDROW HEMP_SWATH " aiNode="unloadTriggerAINode"/>
so foragewagon can be used if we need.
As said if you want i have a look at the productions to see if that need balance I need to know if we stay with the values I gave in the file or not.
they are in column, the MAIZE2 line show the meaning of the values:
MAIZE2 "name of the crop/product"
pricePerLiter="0.690" "ingame basic price for 1 liter (no bonus/difficulty etc...)
harvest litersPerSqm="0.92" "the ingame basic value for harvesting 1m² of the field (no bonus/fertilization/lime etc..."
liters/Ha = 9200 "same ingame value but *10000 1Ha=10.000m²)
money/Ha = 6348 "what we earn in saling what we harvest directly (price/liter * liters/Ha then)
So you can see what will pay the more for 1 Ha field, how much cost a liter of a product for your productions factorie etc...
For spinnery i'd say both. less than 50.000l/ha and less than 12.000l fabric output. To give you an idea with what I used with my crops/spinnery my fields give around 35000/ha of fibers my spinnery recipes for fabric is 6 for 2 (keeping your 100 cyclesperhour) then 14400l fibers for 4800 liters fabric. At your flax fiber pric it would be 4608€ of fibers becoming 19200€ of fabric (14600€ benefits for your factory 175.000/year if enough fields, nothing crazy IMO (and I see it pays your 200.000 spinnery between 13 and 14 months, not cheaty nor too heavy)
