How can i prevent players placing crops on the same farm plot location?

(insert something here that gets me 10000000000000000000M rep)

Hi, its a me! BashGuy10. After playing a lot of farming games, i had inspiration to make my own, one of the problems i've encountered is: Stoping the player from placing on the same farm plot that already has a crop.

Does anybody know how to fix this?

I've already tryed using mouse.Target:GetChildren() to see if there is not any crops already placed, but it stops the ability to even place!

Local script

local plr = game.Players.LocalPlayer
local mouse = plr:GetMouse()
local currentobject = plr:FindFirstChild("CurrentObject") 

local UIS = game:GetService("UserInputService")

local activekeycode = Enum.KeyCode.B
local active = true

local frame = script.Parent.Place
local rp = game:GetService("ReplicatedStorage")
local crops = rp:WaitForChild("CropModels")
local event = rp:WaitForChild("PlaceCrop")

for i, v in pairs(frame:GetChildren()) do
	local model = crops:FindFirstChild(v.Name)
	
	v.MouseButton1Click:Connect(function()
		if model then
			if not active and currentobject.Value ~= model then
				
				rp:WaitForChild("ChangeCrop"):FireServer(model)
			end
		end
	end)
end

UIS.InputBegan:Connect(function(input)
	if input.KeyCode == activekeycode then
		if active then
			print(active)
			active = false
		elseif not active then
			print(active)
			active = true
		end
	end
end)

local plantdb = false

mouse.Button1Down:Connect(function()
	print("yeet")
	if active and not plantdb then
		print("yeet2")
		if mouse.Target.Name == "Plot" and not mouse.Target:GetChildren() then
			print("yeet3")
			
			event:FireServer(mouse.Target)
		end
	end
end)

Server script

game.ReplicatedStorage.PlaceCrop.OnServerEvent:Connect(function(plr, target)
	print("yeet4")
	local clone = plr:FindFirstChild("CurrrentObject").Value:Clone()
	clone.Parent = target
	clone:SetPrimaryPartCFrame(target.CFrame)
	print("yeet65")
end)
