It's hard to tell with it being so early but after flipping through my handy growers bible (jorge cervantes)it looks like it could either be potassium, magnesium or sulfur. Potassium will make little dots on the leaves later on and most of the leaf will be yellow. Magnesium and sulfur look very similar. Mag. starts to yellow the leaves then browns the tips like in your pic. Sulfur basically does the same thing but the leaves lose a lot more color than mag and looks like they even start to curl after a while. So in my limited experience I'd say Magnesium
sorry for the long post lol but hopefully that will help.
nice looking plant btw

Well if the Mg is locked out then feeding it more only makes the problem worse. If it was just lacking in Mg then yah, feeding it would help, but if the plant is locking out the nutrients you need to solve the lock out first, then the plant can properly uptake the nutes it needs.
