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.
do you have ph down? what exactly aren't you sure about? and for the most part it's down to ppm of your water. if the ppm rises- to much nutes( higher water up take, ppm drops not enough( low water up take), ppm stay the same - perfect water will drop and ppm will be balenced.
I am not sure if I mixed the 3-part nutrient correctly. I do have pH down but I didn't think I would need it since "pH perfect" would make me assume it wasn't needed and that made me think that I did something incorrectly.
What pH are you aiming for? 5.8 - 6.0 for DWC I thought for availability in h2o... I stopped DWC for many reasons but issues like this are mainly why. Good luck mate. If it doesn't work out, try a coco coir/chunky perlite grow. Sent from my SM-G955U using Tapatalk
