Stonerdanswered grow question 4 years ago From the looks of it seems like she is suffering from Potassium (K) deficiency! with lower leaves tips yellowing, mottling, and eventually dying. Increase the macro-nutrient uptake by checking for optimal pH (5.5-6.5/ 6.0-6.5 for soil), putting more of the NPK fertilizers (focusing on PK) in the irrigation solution, and making sure there's enough drainage with at least 20-30% of the irrigation as runoff to prevent salts buildup!
Other than that plant looks nice with great potential!
Good luck and happy growing :)
