Problematic Plants

[Kukutyin]

Hey, i recently started to grow indoors (grew hella trees outside) under led and ran into a few problems.

Its a sog from seed, and they got planted into 3dl pre-pots.. 40% coco (may not be the best, and not washed it out, only added cal/mag) rest is a mix of black turf and not so rich soil and added 2g/l NPK to the mix.

I was running it with tap water which could be around ph 7. Some purpleish yellowish symptoms appeared after the first week on some of them now like half of them has it. I vegged earlier in rich soil indoor to prepare them for outdoor growing but they are nowhere as vigorous in growing now, clearly withering.

The pictures shall speak for themselves.

If anyone could provide help, i'd be grateful.

I don't know anything about the medium being used but they do look overwatered to me.You say your tapwater could be a ph 7 I would find out exactly what it is and you should consider using an R/O filter

coco can be full of salt and really screw things up

Those plants need food and proper pH.

Exactly

The yellow and dead leaves are pretty good pointers that they're not getting enough N

What're you using for aeration? I might be missing it in your original soil description, but it sounds like you might want to add some perlite or rice hulls to your soil mix.
