Burmeseanswered grow question 4 years ago Hi there, You can know how to feed by checking your run off ppm(EC).Check your water ppm before watering and check again run off ppm.If they are not much in different, you are good.If run off ppm is very lower than your water, you need to increase your feed next time you water.If run off ppm is very high, you need to reduce.For your pot size, I would say watering once in every 5~7days would be enough or let the top soil to be dried about an inch to two which is also similar to pot weighing method.By checking your run off, you can know easily whether you need to feed this week or should reduce or should increase.Happy Growing... ✌️
