Hi, newbie here. I got pineapple kush in week 5 of flowering, I got some brown spot on the leaves, so I did water feed with overnight tap water ph around 6.5 and the runoff ph is really low like around 5. I assume its ph lockout, so if I want to flush my plant, should I give nutrient feed right after the flush or I should wait till the soil is dry then feed. I am using ocean forest soil in a 3-gallon pot. Any help is appreciated.
