yellow leaves in coco-peat

[Livo]

hey guys just a quick question, my seedlings are only 2 weeks old in coco-peat and perlite mix 70-30 roughly, they've just started getting their 3rd proper leaf set and i've just started using nutes about a week ago (2ml as it says on the bottle for seedlings) they started loving it bursting with life and now going yellow, now would it be that i just need to flush or coz im not using coco nutes?

 

thanks guys

I'd be flushing thoroughly then starting them on a decent coco nutrient, should make all the difference. It could also be high pH so make sure that it is somewhere between 5.5 and 6 for your flush water and feeds.

THC is probably right, but a few pics would give us a better idea of what the problem could be.

If you are growing in coco you need coco specific nutriments.

Hey this is happening to me currently. Im using two mediums though atm 1 100% coco and the other 50% perlite and 50% coco. ID say a third of the 50/50 seedlings are yellow even though the've all had the same treatment. SOme are powering some yellow some inbetween. Go figure......

 

Most of my seedlings in 100% coco are spot on , not showing any defs. etc. As the've said ph flush and refeed 'n hope for the best. I find plants usually become good the more root system they've filled out.

 

Good luck
