I can't give you much of my opinion as I am too an amateur at this hydo game. What I can do is show you what I use and do.Hello, How is everyone?
I'm having some issues and am really unsure how to deal with them.. These are my first 2 DWC plants, I am following the "Useless" feeding schedule (I'll throw a link in at the bottom incase you aren't familiar).
Heres the rundown: My plants have been doing great till about 4-5 days ago, I started noticing the lower leaves yellowing with dark spots on them, its progressively getting worse, first it was only on the plant to the right, now its showing on both plants. I am really confused... looks like potassium difficiency if I followed the "Diagnose your plants" websites properly.
Also, I believe I have root rot, but I have done everything in my power to prevent it, very confused.
My Set up:
- 1 plant / 5 gal bucket - Hydroton+General Hydroponics Nutes. Currently On Week 2 of Useless Schedule: 10ml Grow / 5ml Micro / 3ml Bloom per gallon of water - Currently @ 850PPM
-I adjusted the ph to 5.5 a day after water change, right now its sitting at 5.9-6.2 (variance between buckets), I use GH PH Down for lowering PH. I change my buckets water every 2 weeks at the latest, sometimes even earlier.
-I am running 2 air stones per bucket running off of one 971GPH commercial air pump. I've been told by the guy at the hydro shop that hes run much more on less, can this be confirmed? do I need more air? It looks like its majorly boiling in there. Whats the optimal amount of air for a 5 gal bucket dwc?
-I add 2ml of 32% H2O2 per gallon of water - this is 8-10ml per bucket, each 3-4 days when I recheck PH. Bottle says I can add up to 3ml per gallon but was afraid, as with most nutrients, they tell you to use alot.
-Temps stay at 70 or below pretty constantly, I'm told 68 is best, right nwo its at 69.1 degrees.
I was told that GH Micro and especially GH Floricious would stain my roots (I used it once and freaked once I saw the brown roots, never to use floricious again) so now I will only use the 3 part, bloom/grow/micro. I believe this is more than staining though, theres a swampy smell, even though I've followed all the rules! What am I doing wrong?
To me the problems look like potassium difficiency, as its the only place where I've heard of Red stems+spotted yellowing leaves with brown necrosis spots. I was told potassium difficiency is rare in hydro... so I'm literally stumped and at the mercy of rollitup. Maybe root rot is my only problem I dont know, Total noob here.
I was also considering adding Cal-mag to my regimen, would this be necessary?
Please tell me what this is and how to fix it! Save my precious ladies! haha Thank you so much! Here's the pics.

I have only had a few issues arise and I believe they were my errors to learn from and not because of the schedule I'm following. Dropping in ph down through an empty net pot area and right into/onto roots in the res. Kepping the ph too low/ afraid to add too much, ph was kept between 5 and 5.5/ thought that it would naturally rise, it did not. Rusty, burnt, yellow, brown, and red spots on some leaves. I think that I was locking out nutes because of the ph imbalance. Those have been my only bad experiences thus far and the girls are looking good and growing great. I am going to switch to the Lucas formula for flowering and next crop I'm going to use it throughout the whole grow. I have only heard and seen great things with using that tea recipe you are now using.
Here is the site that explains the nutrient schedule more in depth.
