is this nute burn or sumthing else

Hi there neef help with my seedling it has brown tips and yellowing it started a few days ago and i thought it was heat stress but it was only under a 9w cfl so a day or two after tht i found it could be boron deficincy so i gave her a very weak feed and it stopped yellowing yesterday i gave it a wee feed again and tht but now today i jist put up my 300w dual spec cfl and the yellowing is getting worse plezse help and hers some pics of her the new leaves are growing well and looks like they mite have 3 fingers on these leaves

Can anyone help??

HOw old is she? I started giving my seedling nutes the day after Week 2.

She s about 11 days old ??

She shouldn't have any nutes just yet then.

Most likely it is nute burn. Not sure what procedure is for seedlings, but when nute burn is present in more mature plants, you flush the pot with 3x the amount it holds. example: 5 gall pot, 15 gallons to flush. 10 gallon, 30 gallons to flush. This rids all nutrients in the soil so you can get started on a clean slate. hope this info helps somehow.

So what can i do for her should i just let it dry out a bit and use water or flush it out cos the new leaves look really healthy

I would just let her be. You're u don't want to drown her and that rockwool will hold a lot more water if you try a flush. Make sure the rockwool is still damp to the touch, and just let her go til transplant

Ok thanks how much longer do u think it will be till she starts to show roots ?? And how far should my plant be from my 300w dual cfl

Cfls run cool. So a couple inches away. As long as your hand can't feel heat, she shouldn't. I'd say another 7-10days. You want a good amount of roots before you transplant

Thanks alot everyone
