I'm sure one of the "coco" guys will pop up and give you some advice. But they kinda look alright to me for 2 weeks.

Thanks pal but it's all the browning/yellowing of the leaves that is concerning me

Any possibility that you might have spilled nutrients on those leaves?

Looks like nutrient burn from remaining on the leaves after watering.

I'm not familiar with the products you're using to feed, but do either of them include base nutrients? They look like supplements to me. Also, 60W of LED at 14 inches is a lot of light, especially on seedlings that appear to be struggling. My guess is that they're overlit and hungry.

Thankpal no they've not got base nutrients in, the feed chart im following says to use this for the first 2 weeks, so do you suggest starting them on a and b and raise the light a little ?

I would. I run 100% coco and give my seedlings 1 EC (500 ppm on the 500 scale) of base nutes from the beginning. I'd actually double the light height and see how they do. Adjust based on how they like it.

Did u buffer the coco? If it’s not Canna Coco Coir or one that has been buffered that may be the issue. Also even with Canna Coco I still at a little extra Calmag with nutrients to the coco before I put anything in it. How often are u watering? Cause when there young like that every day is not needed. 250 watts at 14 inches at 30% may be a little strong for them either lift the light up 4 more inches or turn it back to 20%.

Also cookie strains can be very sensitive and being u have a lot of cookie in that cross I would dial everything back.

Cheers pal I'm using the canna professional coco, as for the watering I've just been feeding them when the pots feel dry, every couple of days at the moment but I'm gonna raise the light and start them on a and b

I thought you were never supposed to let Coco dry out. Just my two cents.

I don't mean dry out dry out I just mean the top of the coco it's still damp underneath if I stick my finger in it
