Help me my leaves are turning yellow

Hi,guys and girls.i am growing a barny farms pineapple chunk and blue cheese plants they are 6weeks in to veg from seed.my problem is that some of my leaves are turning lime green to yellow with some brown edging.I don't know if it is nute burn or something else! I have only feed them twice the first time in the 4th week and 5th week with hydro coco nutes 2ml per 1l of water. i use a 300w led light panel I have flushed the plants the pic is my avatar so please could anyone with any info leave a comment with great thanks
 
Calcium deficiency, add 1/teaspoon of dolomite lime to 1l of water, foliar feed just before lights off, then wipe the leaves on lights on to get rid of any salt/water left, foliar feeding recovers them faster than applying nutes 2 the roots, well this is if ya pH and ec is alright

So lets start from the begining. What soil are they in? Soiless? What lights are you using? 6 weeks? How often do you water and how much?

This should be an easy fix. If you give details...like what ppm you fed at, and how much you gave them.
The most important detail is the soil, if you can specify the soil the nutrients are easy to guide yout hrough.

It my avatar the pic on left
I have more experience diagnosing organic plants, but it appears to be overfed. Hard to tell from that picture.
I'd bet money if you transplanted into fresh soil it'd recoup. how big is the container?
Watering once a week leads me to believe your container may be too large, or nay not be draining well enough, you did mention it had extra perlite..
I can't even tell how big the plant is, I really am sorta handcuffed to help based on the information and picture.
But you are new at this... most common probs for newcomers is "too much"
(too much nutrients, water, soil, care (mucking with ph or flushing needlessly)

Hydro coco nutes and the plant is 20inchs thanks for the comments
its probably going to be the coco nutes being used in soil, i did it years ago when i had a bottle of coco nutes left over, used em on soil plants n shit just all started going wrong, soon as i put em back on soil nutes they livened up n recovered

just go to any local shop n get a bottle of tomato food to tide you over until you find better soil nutes, ive done most of this grow on a £1 bottle of tomato food n plants are fine n stinking

You may also want to consider, and i mean this as a last resort btw, it will probably take less time to germinate new seeds and get them vegging than it will to get these sorted out properly,if they recover fully at all, sometimes if you have spare seeds/clones its easier to just bin em n get a new lot going than it is to waste days/weeks on 1 or 2 problem plants, not all the time tho so bear both sides of the argument in your head
 
The bottle of nutes I use it says for soil but I will take your advise and get myself a bottle of tom nutes thanks for your support I will let you know what happens cheers mate
