Help! Heavy Wilt Overnight After Res Change

I noticed some rust spots starting to appear on the leaves a few days ago so I decided I needed to do a res change since its been two weeks. I thought the spots were an indication that the plants wanted more nutes. I did the res change last night, upped the ppm from about 650 to 750, pH was right around 5.5 from 5.9 in both buckets. I am using cxhort nutes and I added 3.0 mL of Wilt Guard (0-12-14) and Growth Enhancer (11-0-0) for the first time in the nute bath. I was only using Hydro A (2-0-1) and B (1-4-4), also Bio Balancer (1-0-0) and Regen-A-Root (0-0-1) in the early veg stages. When I went to look at them this morning they were both wilting pretty bad, as the day goes on they are just getting worse in terms of wilting.

I am not sure if they are shocked or stressed from the added nutes? or upped ppm? pH drop?
Or if the rust spots are causing the problem?

Well it looks like the beginning of a pythium infection. That could also account for the rust spots as root health problems often show as nutrient deficiencies. Are you running sterile or with bennies? Looks like sterile, what are you using, H2O2, pool shock???

Also, was the water filtered or tap?

First grow so running sterile and tap water, don't know much about bennies. Haven't added any h202 or pool shock, what do you suggest doing?

Tap water is definitely not sterile and would be a likely source of the infection. With DWC I highly recommend RO water. To run sterile I use pool shock, it lasts a long time. 0.04 grams per gallon is all you need. Refresh twice a week. Some like H2O2.

What are the nutrient temps? Warm water can't hold as much dissolved oxygen as cool water.

I don’t have access to RO water at the moment, should I switch to distilled for now? I haven’t checked the water temp, the temp in the grow is 72 degrees. Should I res change with distilled water and add some h202 which I have currently?

You could get RO at walmart in 5 gallon jugs pretty cheap.

Using something to keep the res sterile is recommended. There are plenty of threads about the options on here. See what works for you.
