I have a 2 and a half week old seedling that has had the leaves turning yellow over the last week or so, can anyone give me advice on why this is happening?
Have a look here its got loads of plant illnesses http://www.thenug.com/galleries/diagnose-your-sick-marijuana-plants
Nothing in that really seems to match, all the new growth is fine it is just the first set of leaves that grew after the cotton leaves.
My white widow plant started going yellow and brown tips, so i replanted in coco over the weekend. Seems to be getting better the new growth is green but old leaves staying yellow. Hope mine dont die :/

If it yellows from the bottom working its way up you have a nitrogen def. Brown tips may sugest too much nuterients Or you have possible lock out from salt build up in your medium and depending where you get ya coco coir from it could alrady be full of salts.. auto help page http://forum.grasscity.com/index.php?/topic/1294434-Need-help-with-autos?-Welcome new vote page http://www.dutch-passion.nl/en/photovote/2014-04-05-autoxtreme%C2%AE-loki_1624/

Ahh well I have no PHing equipment and I didn't rinse the Coco for salt so that may have attributed to it, I have a second seedling that is getting the brown tips on the leaves so I may have used too much liquid fert but either way until I can get my first outdoor harvest done I am going to have to just use a standard potting mix and forget the Coco as I cannot afford all the crap that needs to go with it.
