I dont. I like to taper down the nute strength the last 3 weeks or so. But the plants decide for me. If too green water only. If fading light dose of nutes. You nist dont want over fed plants. But the last two weeks is when they pack on the most weight, resin and density so i dont like to starve them.
Hope that made sense. And if you are not comfortable tailoring your nutes to the plants needs yet ues feed through week 7 or 8 and water only after that.
