HELP! Leaves slowly turning yellow, dying, also seems to be burning at tips.

[blueberryOG]

Hi growing in coco coir with canna coco nites a+b and calmag.

I feel it has happened since I placed clone into the coco coir.



I’m not sure whats causing the yellowing of the leaves it seems to be getting worse.

I water every twoish days when I notice the coir drying out and I have been feeding roughly every other watering, to avoid giving it too much nutrients.

inside a grow tent, and with blurple lights.

I just need to diagnose so I can correct. Can anyone guess whats going on?
