"You have reached the maximum number of Slimes allowed on your island. (2)" does this affect afk rates

[IOmee]

I have 27 t11 slime minions with diamond spreading, corrupt soil, lava bucket, budget hopper and when im afking my minions with my magma cube pet I get a notification that i have max slimes on my island so i was wondering if this was slowing my rates and if you could suggest any upgrades please do.
