This is my first grow and honestly have no idea what I’m doing. Watched a couple canuks videos on YouTube and figured i could do it. So I order 4 seeds from canuks seeds. 1- sour diesel 1-amnesia 1- zkittles and 1-gelato. I’m kicking myself in the ass for doing his way and not germinating the seeds first but I just threw them in the dirt. I’m using a soil/medium called just add water. So they all popped at different times, sour diesel being the last. All 3 were off to a great start until sour diesel popped up. Then it seemed like everything stalled. The sour diesel is now going on 5 days and hasn’t gotten its first leaves. Also the tips on the amnesia are yellow/brown. Please help!!!!!
