Deficiencies in autoflowers

[Boru420]

It is always better to be modest than to add more. A plant will not die from too little nutrients, but it won’t survive an overdose. its strange the lower leaves look darker than the upper ones, are you spraying anything directly onto the leaves,

Hey guys I have some deficiencies on one of my Northern lights Autoflower.
I grow in coco coir and I feed once a week. I use general hydroponics flora bloom and micro, and CANNA cal mag.

My feeding per gallon is:
Flora bloom (0-5-4): 8ml
Flora micro (5-0-1): 4ml
CANNA Val mag: 1.5ml

I always ph my water in a range of 5.8-6.3.
Does anyone know how I can fix this deficiency? Thank you for the help!

Feed 3 to 5 times a day in coco

Salt buildup is real. Learning the hard way I am. But a good flushing and restart can work.
