tip yellowing

hello, i am having some problems with my plant

the tips have been yellowing since about 2 days ago. i am growing outdoors, and i have no explanation... the soil pH seems to be good. its around 6. as for other nutrients, i mixed in some 10-10-10 nutes to see if that would help. although yellowing has slowed down a little bit, its still going on...

any help would be appreciated

ah yes, im growing bagseed in soil... it is about 2.5wks old.

What kind of soil is it? Some soils are to rich for delicate seedlings....

it's a mix of mainly clay and silt. i also added some perlite in the mix...

Did someone give you the recipe for that? Silt is the sediment from the bottem of ponds that erroded from the rivers and streams that feed it. Who knows what's in it. That may be your problem....

well, truthfully, i dont really know whats really in my soil... all i know that there is more clay than anything else. and no, no one gave me a recipe lol . i wanted to see if my backyard soil, mixed in with some miracle-grow potting soil, would be good. seems like its not
