What additives and nutrients are you using?
Water source?
pH?
EC/PPM?
Water temp?
Looks like straight up lockout. What are the conditions of the roots? White and glistening? Any signs of slime or other nastiness on them?

What order did you apply the nutrients/additives?This is what I just used for my water change yesterday.
At this point I checked the PPM and it was at 400, I added an additional 5.5ml of both Grow A/B to get it to 550PPM and then I used General Hydro PH Down to get the PH to 6.1. My water source is distilled water. The water temp is currently at 66 F.
- General Hydro PH Up : 1ml/g
- Botanicare Cal-Mag : 4ml/g
- Cyco Grow A : 5.5ml/g
- Cyco B1 Boost : 3.8ml/g
- Cyco Zyme : 3.8ml/g
- Cyco Grow B : 5.5ml/g
- Cyco Dr. Repair 3.8ml/g
The order I wrote the nutrients out, is the order in which I mixed them into the water. I am definitely going to look at the thread you mentioned.What order did you apply the nutrients/additives?
.6 pH rise overnight is pretty drastic (i just went through hell with this myself). You may want to read this thread by @Aqua Man for the absolute best explanation I've seen on how to start a fresh res or do a top off.
As for the original question of the thread, enzymes are known to cause foaming. I'm not sure that you need the Dr. Repair either, it's an iron supplement from what I can tell, and may be causing more harm than good at this point.
I was told by Cyco to not use silica in DWC until last half of flowering due to it causing too much PH Fluctuation in DWC environments. I got the idea of adding PH up first to add alkalinity to the water by @Aqua Man. In what order should I be mixing the nutes to make sure I don't get lockout?Have you noticed if there's anything in the bottom of the res? I'm wondering if perhaps something crashed out because of the order of application, or perhaps incorrect starting pH.
Why did you apply pH up initially? Was the pH of the water really low to start with? Ideally you'd start with a pH of 6.5 and correct to where you need it after adding everything. If using silica (doesn't look like you are) pH to 6.5 after adding the silica and allowing to mix for at least 15min.
Also to be clear - If I had a PH Controller / pump in my set up, then I would use the silica but because I don't that is why I'm not using it.I was told by Cyco to not use silica in DWC until last half of flowering due to it causing too much PH Fluctuation in DWC environments.

On that note, when should one stop using silica? I've ran it since the start, just curious how long before harvest one should stop using it.Same. I use silica until late flower.
When I do the foliar spray, I only need to use PH'd water and the silica additive right? I don't need to make a complete nutrient mix for the foliar spray since those nutes are in the water?Sounds like you corrected a few things today. I agree with the Cyco rep, silica probably throws off their pH buffers that obviously do a fantastic job by themselves. I'd still do the foliar during veg per their instruction as it is bar non the best additive I've ever used in terms of influencing plant structure and resilience to stress.
Keep us posted, sounds like you're on track now.
Correct. Make up the silica solution, pH, and spray. Do not add anything else.When I do the foliar spray, I only need to use PH'd water and the silica additive right? I don't need to make a complete nutrient mix for the foliar spray since those nutes are in the water?
I use silica through my rdwc and do not have a problem. I run floraMax for the last 2 years. They are considered as a synganic product. My ph stays pretty stable. My silica is the next to the last thing that goes in only one product after beside my enzymes and denies with microbes. After that my ph is a little over 7 bring it to 5.8. If it rises sets steady at 5.9. The way you mix your nutes will greatly affect your ph if mixed wrong. I learned that the hard way. On my first grow my ph would climb to damn near 7 from 5.8 over night. I did some research and found out I was putting my silica in at the wrong time. Sine then I have not had an issue. Another thing that will GREATLY affect your ph is to much air in you bucket. One thing temps in your bucket will affect ph as wellI was told by Cyco to not use silica in DWC until last half of flowering due to it causing too much PH Fluctuation in DWC environments.
