Ok so I have 4 northern light plants in mid flower now they are autos. The leaves were looking like I have nutrient burn on one of the 4 plants and a K Deficiency on all of them they are spotting some worse then others. So I freaked out and flushed all 3 pots with 3 gallons of ph’d water with florakleen checked all runoff and the plants are all around 600 to 900ppm ph is ok hovering around 6.4 one plant is right at 6. All in ffof soil using gh nutes using the Lucas method for feeding. Do I wait for then to dry out and go back to normal feeding or should I give them a watering with some nutes half strength now while they are still soaked? Thankyou for the support.
Play it safe, wait.
