Re: Fertilizer Issues.
Out of the above questions i can confirm the following;
It is not the cooldown delay for using fertilize crops.
Other actions such as talking watering, etc can be performed.
I already tried moving the planters as i stated in my OP.
@SheriGR I'll try and get you some further evidence when i'm home however i'll be out of the house for the day so it may take a while.
Thanks!
