First Grow...unhealthy babies and help is needed.

Hello,
i germinated 2 seeds of cheese 18 days ago and planted them on coco...
they were doing fine in the early days, but i was watering with tap water which comes with 280ppm and a ph of 7.4-7.5. like a good newbie when the second set of true leaves appeared i fed them slightly strong @ 400ppm with the same tap water so 280ppm from water and 120 from nutes...they got a little tip burn as you can see from the fotos but i reverted on just ph'd water and there were no signs of nute burn anymore and they were growing even though appeared to me a little bit slowly. then they began twisting their leaves and had some strange irregular spots of lighter green almost yellow on their new leaves( you can hardly notice them on the second set of true leaves)
So 8 day from seed they had third set of leaves and i began feeding 3 part GH Flora line @300 ppm ph'd @ 5.7 even though i noticed that my meter was reading my tap water differently @ 8.4 so it appeared that it was reading a higher value of ph... i did not calibrated it immediately and continued the next feedings with the same meter and same ph @5.7 and bumped to 315ppm the twisting did not get better but growth continued ...
i Transplated in their final coco hempy's after 13 days from seed and fed with 340ppm water(280ppm tap water and 60ppm nutes) and calibrated my meter and ph'd @ 5.7( before i think the ph meter was reading a higher value so i thought i was feeding 5.7 ph but probably i was feeding the babies @4.7 ph the first times)
last time i fed them @350ppm and ph @5.7 i even added 1 tea spoon of mineral magic at the base of each plant... but here we come to today...
i hope you can tell it from the pictures ... the 2 babies have some pale green leaves and going yellowish ...
there is new growth though and they seem to progress but so seem to progress their yellowing trend
i don't know if they need more nutes even though i plan to bump my next feeding to 450ppm and see if they just needed some more food... until then i will be more than grateful to anyone with advice ...
Thanks...

have you pH'd your run off?

How long between watering?

Personally I think you might be neglecting the K.I.S.S. principal.

I am exclusively an outdoor guy myself, I have never pH tested water. I mix nutes to what is on the bottle and my girls get watering with the hose... Just saying don't over think things especially in soil

Edit: looks okay to me aside from being a little yellow. An in proper pH could be the culprit for locking out N

Is this indoor or outdoor?

My bad i did not give sufficient info...
This is an indoor grow and i've been watering every 2-3 days
the temps in the tent are day temp from 78.5F - 83F and night temp around 73.5F - 75.5F
Relative Humidity is fluctuating between 40% to 55%
medium is canna coco with Grodan Grow chunks in the reservoir( ph'd before use to 5.7)
i tested runoff the last feeding and it came @350 ppm and 6.12 ph it was similar albeit a little higher the feedings before.
i really don't have an idea of what the K.I.S.S. method is but i will inform myself.
i am maybe a little over worried since it is my first grow but i really think they are not really healthy...
thank u anyway for passing by.

They really don't look that bad.

Need more N and less watering, but besides they're fine.

i would agree.

I will definitely feed them more next time(more of the grow part) and i will also let them dry a little more...
i just thought i could speed up their grow a little by feeding them every 2-3 days since they are in coco hempy's and i could not overwater them....
i was thinking today that changing my light from cfl to leds maybe caused a little stress also on them which they manifested like this... could it be?
let see how they would look like in some days... thanks for the replys...

if you want to speed up the grow its best to only feed when they want it.

Thanks for the input man... i really thought that in coco hempys you could water every day to speed up the growing process... i just read it and saw it around the web... so i choosed smth in between and was watering every other day... i will let them dry more now and see if its true that in coco you should not let it dry out to much because of the salt building up... anyway i guess experience will answer the majority of my questions.by the way the babies look a little bit better, new growth is greener
Regards.

So far they look good it does look like they a little bit of Nitrogen. I had the same problem when I first started. Make sure water leaks out of the pot when you water and that you stop once it does. Chicken shit is high in nitrogen but can burn plants if not diluted properly. Fish remains also very good! You should be able to get fish emulsion by your local store. Just read the directions and have patience.

Other than a little pale she looks healthy!

hello...
babies looked like they were catching up and feeling much more wealthy but then i noticed some yellowing again... new grow especially on the one which is a couple of days late(left one) is manifesting some purple/red-ish in the center of the new leaves (the one on the left...) Foto _1301
some close ups in which you can notice leaf twisting, some of the leaves are not straight and overall they feel crispy...
Foto_1295 & 1297
Here you can see some rusty lines between the veins of this leaf even though its not clear in the foto and also the leaf twisting...it's much more visible for real though...Foto_1296
this is the healthier one ...the one on the right...Foto_1298 & 1299 even though this one also is showing some of the same signs...
this is another foto of the smaller one in the left...Foto_1303...
I tried and searched as much as i could and came to the conclusion that these are signs of cal-mag deficiency...this would not be strange since i'm groing in coco hemys although i'm using tap water and it comes in 280ppm of whicha good part is calcium and magnesium but i read that calcium from tap water is actually not very available to the plants because of the size of the molecules
but hey i don't know anymore this is why help is mucho appreciated...
Thanks in advance.
(i'm having a problem uploading fotos...)

Purple on leaves means temp issues. I know this because my outside plants always have signs of purple at the min. Temps go from 20-30c day to 6-15c at night. They're not a fan of such a drop.

Thanks man ...but in my tent the temps are constantly from 25.5c-28.5c lights on and 23.5c-24.5c lights off with a RH rangin between 40%-60% ... i think this is good. this is what my igrometer usually shows
Edit: i'm considering anyway to try another one ...just in case this one is faulty...

C'mon some input to get these babies healthy...

Well even if i'm not having a lot of advice i really need it so ... i'm insisting...
hoping someone will help...
it came out i was underfeeding... so i uped my feeding to 7ml of micro ,7ml of grow, 7mlof bloom.... this put my nutrition solution to 600ppm (280 of tap water and 320 from nutes) and they are getting better but i noticed some strange holes and one of the first set of true leaves on the other was like this...
then i saw that some the rusty spots had turned into holes....like this
some overall fotos of the "sintoms"... i don't know what this maybe... but maybe i have to act fast so... help please
.
overall health has improoved...

i have not seen any bugs around so i don't know what it could be....
overall health seems good...they are on 26 days from sprouting... any advice or suggestion is welcome...

You have a bug problem. Spider mites most likely.

how can i confirm this ...i don't see anything ... there are no visible little bastard in the tent
eventually how can i solve the problem...
never thought i would have to deal with spider mites in my first grow...
i want to fucking burn these motherfuckers
thanks anyway man.

Look under the leaves. If you see tiny brown/black dots they are bugs/bug shit

i did look man... did not find anything...
could this have been caused from underfeeding them dor several days...???
i don't think spider mites are hiding from me...even though it could be this is the begining and they are not in grat numbers , let's hope not anyway...
