Cute girls my friend, welcome to 420.
That light 600w 30 cm away 12". I would start there. A t5 fluorescent is more than enough. Move that light away, and start with some lite nutrients and they should come back to normal.

Canna coco is just plain coco right? Those girls need some food coco is inert. PH for coco is 5.8 I believe. Not a coco grower though. I use pro mix hp cc which has coco in it but also has Pete dolomite lime and perlite.

when I start my seedlings I pre soak the medium with a light nutrient dose.

I have used a number of things to start them including just megacrop and about 2gs per gallon. Usually I use thrive alive b1 red at the recommended dose and pressing the medium with that. You could just use a light dose of whatever you hve at their recommended use for seedlings.

Feed at lower dose like 1/4 strength nutes to start with. Coco is not the same as soil and coco cannot be allowed to dry out. Most here use special nutes since the big box lawn & garden stores don’t have suitable nutes. Geo flora organic dry mix nutes or mega crop but these require time for shipping. Do you have grow shops near you? Be sure to get nutes designed for coco or hydro, again coco is not the same as soil so get nutes designed for the grow media you are using. Since most nutes only deliver NPK but not calcium or magnesium you will also need to have cal-mag on hand, plus your ph tools like test strip or pen and of course ph up & ph down.

Personally I would check ph first things first and be running light 24 hours until veg and raise your temps 72-76 f constant with humidity around 65-70% until veg as well...seedlings have enough nutrients packed in the seed for the first 2 weeks if you gave them any nutrients before they develop good roots you possibly could ruin/stun the plant indefinitely...I'm a newbie myself but these are all common solutions Ive found during research

I also keep my lights no closer then 30 inches during seedling into veg...I too run mars hydro...these are my latest plants at day 1 and day 12... by day 15 they were already getting root bound and needed transfer

Thank you...I put em through hell first 3 weeks ph was in the high 4s from the start which wouldnt matter much until week 2 but after that its instant problems...if you can zoom in you will see all kinds of blotching and discoloration between veins this is begining a lockout caused by ph rather then burn or toxicity...but I caught it early and the girls took right off once transplanted...word of advice...get a nice digital ph pen stay away from the cheap ones on amazon...good luck
