Currently ebb flow is working excellent! As the plants consume the water and nutes, water level drop. Do I just add water or do I need to mix more nutes with water than add to reservoir?
top off with ONLY water until resevoir change if TDS stays within limits for your grow and you dont show signs of deficiency
Add water only as level drops(daily or so)...check and adjust PH at that time ....then empty and refill res with fresh water and nutes every 7 to 14 days.
