Take my opinion with a grain of salt.. I dont see things the way most do.. Imo, you wont need to feed that plant for about another 2-3 weeks.. If that. You are in organic soil.. With castings added! Thats a lot of plant food! Do you see the yellowing tips on your new growth? That's the start of nute burn.. Which means they are already being over fed.
I dont believe in counting days for this very reason. As a new grower, I'd advise you to try and break that habbit early on. You are already focused on a "date" or time to start adding more fertilizers.. When your plant is clearly saying it doesnt need anything more, and that in fact, it's already getting too much..
My advice is to start learning your plants and really looking at your plants. They will tell you what they need and when they need it, better than anyone on this forum can, lol. The 1st thing I noticed was that nute burn on the new growth.. Listen to the plants bro, not a calendar or bottle.
