14 days old Royal Dwarf starting to show yellow parts

Hi all! its my first auto grow and my second in general.
i`v got a royal dwarf auto in 10 litre coco+perlite soil, 250w Dualspectrum light.
3 fans - deflate, small inflate and another one that blow on the plant.
Temps are around 75f-80f in light time and around 65f-60f when its dark.
humidity is 45-50 most of the time. she looks really healthy till now
but i noticed some yellow starting to show up on the leaves. im feeding
only PH tap water (6) and iv got EC meter that shows 250us.
i`m little bit confused with EC to PPM convert so idk if 250us from the
EC meter is good.

ill try to add some photos later but anyone knows what could be the
reason that she`s start yellowing?

thanks.

what are you feeding it ? and is it the tips yellowing?

yea its the tips but im only watering...no nuts

did you flush and PH the coco before you started ?
and was it miracle grow perlite ?

you might need to feed it brother hard to tell
but if you didnt properly flush your coco then it might be a burn
coco tends to be really salty when you get it since coconut palms tend to grow in really salty area's and its usually not flushed from the processing plant

No man...i didnt flush the coco, anything to do now?
should i flush it now with the plant? take a ph test from the runoff water?

i added some pics, i noticed some small holes on the leaves, i think i have a few options
so tell what do you think :

1. transplant it to a new flushed soil.
2. flush it now. (should ill do it with ph water?)
3. just keep watering with PH tap water (no nuts).

* i don`t see any bugs or something flying in my closet.

and thanks man, youre really helping me here.

id feed it and see what happens the chrome type yellowing i would think is it showing its hungry
the yellow line ive had house fly's do that hard to tell
and the holes look like and injury when the leaf was still young or it could be a sign of a deficiency

i forget what it is but one of the nutrients makes slashes / tears in the newer growth when its hungry

the thing with coco is if you dont load it with nutes of some kind then you need to feed it seeing how its dam near inert i use a handful or two of worm castings mixed in and this will carry the plant until its ready for nutes id start at 1/4 str and see what happens it will probably fix all the issues seeing how its starting to scream to be fed

after thinking about it its probably just hungry man
i was trying to cover all bases before a pic was loaded but after looking at it a feeding probably wont hurt it

Great thanks! so you think that start feeding her with 1/4 grow nuts every second watering will do the the job?
im using SENSI GROW + BLOOM (A+B) and i`v got some BIOBIZZ rootjuice. im really scared to burn her =/

by the way what do you think about my measures?
Tep, ph, hum and all that...

i would just hit it once a week with a water in between is what i do the ones that still seem hungry i may feed twice a week
no need to push them very hard a burn will set you back further then slightly under feeding them most the time

just some lite grow will do the trick when they start to flower some add a bit of bloom to the grow then after flower is really setting in then cut the grow and up the bloom

Thanks again..ill try feed her once a week and watch how she`s taking it.

so 2 days ago i watered with 2ml SENSI grow nuts (A+B) for 3 litre of water
trying to stop her yellowing, still can`t see any change but want to know
what do you think about her - size, color etc..she`s 18 days old and i want
to give her the best and to get it back later

thanks
