Im not trying to rain on your parade like you think everyone else is, but if your plant truely is suffering from a deficiency/abundance/problem, as an aspiring skilled grower it would be smart of you to look into the idea. in my opinion, a skilled grower can understand and communicate with their plants, when then plant is telling us something, we listen and care for it.

hope everything works out for ya!
