Hi need an experienced growers opinion

[Pinball123]

Hi everyone this is my first attempt and after some research I’m leaning towards a potassium deficiency it’s 23 days old growing in coco with perlite and iv ammended the coco with 444/284 dry fertiliser and running a marshydro tsw2000 it’s seems to have been growing ok but I’m new to this so any feedback is much appreciated Iv got the light set at 24inch ph water at 6.3

Looks too young to have a deficiency. Maybe your water Ph was "off" once or twice?

Thanks would you advice keeping it at 6.3?

@Pinball123Welcome to AFN

Coco and perlite is a hydroponic media and you are treating it like soil. This will not work out well. You are experiencing a lock-out of Mg but the cause is anybody's guess. Go out and research coco as a growing media for cannabis.
