Hey there. What a lovely grow buddy. You are so near the end and have so many healthy green leafs that can be a light source of N that I wouldn't go spoiling what you have done. It's just what you are using has no N in it really and the others are soil conditioners and co2 as the slim is pushing your nutrient uptake to the max, (you are in optimal performance). The little bit of N needed should be there is your healthy growth. As you are using organic and with her been so close, you really outta leave her be. What she has 5-7 days left of nutrients if that. You could top dress with some extra soil that might give you that little bit extra needed?
