Hard to tell with your photos color wise.
But are u letting ur soil dry before watering ? And do u get runoff when u water ? It looks like the soil might be hot .. I'd recommend a flush with just phed water . Get atleast 10% runoff.
Let it dry Fully . Before going to ur routine again.

Best of luck.
@Grow4Releaf, thanks man, I did do a flush last week and waited until they dried completely due to a change of nutrients, I have worked out though that she's a photo period not an auto flower so light has been switched and fingers crossed she will flower 😀 👍
What type of nutrients are you going to be using this crop ? Also if I may suggest checking out VPD & learning about it, Otherwise known as Vapor pressure deficit. It will really help you understand the importance of environmental set-points keeping your plants happy and stress free maximizing on their growth.
Keep it up! If you ever need any help DM me,

I recommend printing off the chart on this website & using it as your reference point. I keep them on the wall of any grow I work. Keep it up fellow Canadian!
