Help! Heavy Wilting Overnight After Res Change

[Jefe-Grow]

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?

They look locked up.

Should I have done less nutes? Looking at that chart based on before the res change they were falling, static, rising. The water only fell a few inches and the pH went up to about 6.1 and steadied. Would they be locked up from adding more nutes?

I only increase by 50 ppm's when adjusting... Thin it down to 650 again and make sure they are feeding... Just react by the numbers they give.

Locked out would be my guess. Probably had a small magnesium deficiency and now they are pissed at the new res change. I would fill them with clean fresh water and let them drink that for a week or so. They’ll be fine.
