I have a humidifier for night time just incase I put it on and set it for 45 but every 2nd day I'll change the water over and nothing has been used so I think it's okay 🤔
The spots started on a lower leaf to begin with which was bigger but since then I defoliated and then this has appeared 4-5...
Rh is set to 55% and I have a oscillating tall floor fan set on speed 1 which is quite aggressive but there's a decent distance between still enough to blow the leaves around
Here is some normal lighting pics no zoom but close ups
Lighting - unbranded led 600w equivalent x2
Medium - Coco coir / perlite 70/30
Nutes - Terra Aquatica tripart - previous known as ghe flora
Water soft Scottish tap watter 0.2-0.3 ec straight out tap 7.6ph
Following labeled nute schedule
Any idea of what could be causing these holes in random leaves if not a mite? There is nothing easily visable apart from the red dots I seen a couple times but nothing has appeared today.
