Moby's pecker DWC

#1 is doing fine or at least it appears or I think. #2 has given me nothing but problems. I am on my 2nd res change this week for her as she had some funk going on with the bottom of her roots in the pale. She seems hungry and foods there with ph at 5.8 but she doesn't seem to want to take any of it up. She's growing but very very slowly. Her roots compared to #1 are a God damn joke and I'm just not sure what more I can do for her due to the fact I am new to hydroponics and dwc and I am not very knowledgeable in hydro problems or problem solving. I'm very keen to learn and that's why i am giving this a try to begin with. I washed the bucket, airstones net pot and roots with a light h202 mist in a spray bottle and a scrub for the materials. I then added fresh water 10L. Added my calmag then my EH trio. After that I applied 20ml of cannazym to help with the fucking war zone root mass that is nearly non existent on #2. After that I added 6ml of hydroguard to help with my roots as well as combat any unwanted stress/heat issues. I plan to Stay ontop of the ph @ or around 5.8 and just let her be. Fingers crossed that something picks up both above the netpot and underneath the net pot. If it doesn't I will just focus all my time on my other tents and #1. I took this on as a learning experience so I'm not stressed about it and I'm certainly not mad about it. I'll be happy if I could just see one of these until the end. IF ANYONE HAS ANY ADVICE OR INPUT , HELPFUL OR CONSTRUCTIVE CRITICISM I WELCOME IT ALL. I JUST WANT TO GET THIS RIGHT AND DRIVE ER ON HOME. until next week , Donkey smell ✌️
