Young Seedlings yellow leaves

[ckp]

Hi all,

Thats my 3 weeks Jack Herer auto that's growing outdoors. Two days ago the leaves started turning yellow (weather on that day went from 15C to 23C full sunny). So far it has been lightly fed with nutrients once.



Any ideas?


Cheers

A plant that small shouldn't need nutrients. What kind of soil is it in?

Some local outdoor organic soil. Never tried it before. Should I replant to regular outdoor coco-mix soil I've used before?

I don't feed my seedlings until they have there full complete set of serrated leaves, and when they do, they go into a 4 inch pot. I grow in HP ProMIx

Guess might be nutrient burn then?

Too much water. Let them dry out and beg for water. Then you can water and feed with an initial feeding at 25% of the recommended product. Do this until you have 3 sets of leaves showing. Then take it up to half the recommended strength.

Thanks for the feedback. It looks a bit worse today. I've cleaned up the soil a bit to allow roots to dry faster.
