COCO COIR Sick plant not sure what’s wrong

[Bigbudbenny]

Sick plant , can’t figure out what’s wrong can someone give me a idea on what’s wrong it’s no taller then 30cm or even less haven’t measured it , think it’s just going on two months veg , it’s my 6th grow and never had this happen before I’ve been doing all the basic on how to look after them watering properly, checking ph , Ppm , temps humidity all that stuff now I have come to this problem pretty much started from the second week of sprouting .

are you reusing your coco , Nutrient lock out will hapen if you are not watering to run off and even then I would do a flush ,check ph run off and ppm as well .
The other thing is did you recharge your coco with cal mag , when I reuse coco I check the ph,ppm of it then flush if needed or proceed I water the coco with double the recommended cal mag amount and water away after that just go back to normal routine

I always use fresh coco from BVB premium blend , I never recharged my coco before even when i haven’t in my last grows I never had this problem.
