So I've done my research and what not but I just don't feel like I am doing things correctly... I have 2x DWC 5 gal buckets (3 gallons of water) geolite clay pellets and root riot cubes. I am 7 days in from seed and plants are under 300 Mars hydro and 4x 23w CFL 6500k. I am using advanced nutrients: pH perfect Micro,Grow,Bloom. Instructions state 1ml - 1 liter of water. I have 11.3 liters (3 x 3.78).however I want to use about 25% the strength so I used 3 ml. pH read 7.8 before adding nutrients. Bubbled tap water over night. I added 3 ml of micro to water, let bubble for 1-2 minutes. Added 3ml of grow,let bubble for 1-2 minutes. Added 3ml of bloom,let bubble for about 10 minutes. Checked pH and it read 7.1. Something just doesn't feel right. Should I just wash out buckets and restart? Just nervous and unsure. The weird brown thing on the leave was there well before adding Nutrients,i have no idea what it is.
