Ive been watering about every 3-4 days. Waiting till they are dry a knuckle deep and i tend to go one day longer rather than one day shorter. In the past 3 I had very light feedings the first 2 waterings with big bloom, cal mag, and seaweed. the past two weeks have been only water due to these issues arising. Last night I fed a 1/2 feed of big bloom/calmag. As well as an Armor SI spray due to one plant having a small powder mildew spot on a stem.
Ph run off has stayed between 6.3-6.6. I have been watering right around 6.3
Fox Farms Ocean Forest with a 20% mix of perlite is my medium.
I feel like there is no way im watering too often due to letting them dry out before watering. I want them to want the water. Also watering until 10-20% runoff everytime.
