The amount of time/mats put into making fertiliser plus the time taken to actually spray the crops should surely justify the crops staying fertilised until maturity.
Having it potentially disappear just feels unnecessary, and makes the process almost redundant.
I made a bunch of the 2 fertilisers to try out and sell, I highly doubt I’ll bother with them again unless this is changed.
Please consider removing the possibility of the plants becoming unfertilised during their growth cycle.
Not everything needs to include RNG!
