bit of advice on feeding, plant yellowing

[din5]

Hi all
first time poster here.
first time using coco coir with 15ltr autopots I am not using the autopots at the moment as watering from the top,
autoflower pheno
just need a bit of advice, ive got a 16 day old seedling
I'm using canna coco coir 60/40 perlite
canna coco a&b at 1ml to 1ltr a&b
rhizatonic at 1ml a ltr
cal-mag plus 1ml ltr
cannazym 1ml a ltr
water ph between 5.8-6.0 done after nutes added

plants starting to go pale green to starting to go yellow all over.
watering every other day about 500ml to 750ml water with feed everytime.
ec around 0.6-0.8
under 300w vipar led panel with 60' degree lenses and pulling 250w from mains in a 2ftx2ftx5ft
temps 24-26c with lights on
temps 18-22 lights off
18-6 light cycle
I got just over a inch of clay pebbles in bottom of pot, 1 inch on the top of the coco coir . the coir does not get dry its always wet/damp when I put my finger in a inch.

now the info I need is obviously am I under feeding?
does it matter the coco coir is damp to wet when I water {I know it must not dry out}

if theres anything I'm missing please feel free to advise me
cheers din5

Feed them more up your ec using A & B and if your using tap water 5ml of calmag+ per 10litres through out your grow.
