Nute burn?

Hi, im a first time grower and im struggling with my 2 seedlings. We’re on day 9 and my bigger one, lime daiquiri, has been doing amazingly, my smaller banana blaze is struggling and although it sprouted first its growth rate has been much slower.
Although I’ve read you shouldnt add nutrients until 2 weeks earliest i added a couple drops of baby bio to my water the other day and i think this is the consequence. Banana blaze’s leaves are practically crumbling away and even my gorgeous lime daiquiri is showing a big patch of discolouration
Should i flush or will that make my problem worse? If i dont do anything will they get worse? I’m using coco & perlite.

they’re autos btw

If you're using coco without nutrient amendments in there then you need to be fertilizing every watering with pH adjusted water aprroximately between 5.7-6.3pH. water enough for a slight runoff. And you'll likely need to add CalMag unless the coco is well buffered. Do some research here and make small adjustments to correct the issue. https://www.cocoforcannabis.com/
Good luck.

i have canna coco a&b on the way, i pH their water with apple cider vinegar, i just added a drop or two of baby bio into the water cos i read it was okay for weed & thought they could use it but obvi not cos they’re so small, it hasnt progressed at all in the past few hours hopefully they’re good

If those seedlings are in coco, you need to be feeding them...right now. When in coco, feed them from day one, until they're done...don't use plain water. Good luck.

Hey, I did the exact same thing and my last post was pretty much identical. I've grown outdoor lots but first time indoor. As the others said here, and on my last post if they are in Coco (mine Coco/Perlite mix) feeding from the start is key. I also read the 2 weeks no nutrients thing but that's not for hydro or coco growing. You'll find as soon as you start feeding them they will literally grow by the day. I'm flowering mine atm and it just made my grow slightly longer but they survived. Good luck

Thanks for all your help guys, so should i start adding the a&b nutes as soon as they arrive? following the directions of course. They should arrive tomorrow

Yea I started with less than it recommended and just tracked it from there in a diary.
