Hello! My Wappa seedling is 2 and a half weeks old, do you also think she's a bit pale? Soil is just coco coir (60%) and vermiculite (40%), gets 5 hours of sun (early morning/late afternoon) and I only water with root juice once every 3, 4 days.
Hi, in my opinion, you should transplant to a slightly bigger pot and cover the entire stem with substrate and fertilize with a nitrogen-rich fertilizer, and you'll see how it will keep growing super strong! Good job, buddy!
You need to transplant this seeedling asap, a half filled cup is barely enough room for more than 3-4 days of root growth.
Root juice is not a fertilizer, so you will need to buy proper cannabis grow nutrients and flowering nutrients too.
