Calcium Deficiency?

I'm running Advanced ph perfect sensi grow with voodoo juice and b52 right now in dwc. Not quite sure why the hell im getting a deficiency since AN says just follow the instructions. The only thing I can think of is that I was running 1/4 strength because it was the first week I was feeding the seeding? After seeing this picture yesterday I changed the res and increased nutes to 1/2 strength. Should I just go full strength? Keep in mind I am already running the additives at full strength (voodoo juice and b52). Any suggestions and do you think the picture shows calcium def?

Climate is fine, air temps are in 70s and water is right around 70 degrees.

Tell us about your light, what type , how close and what are the LUX hitting the plant? If you dont already have a par meter or lux meter you can download a free app on your phone that is adequate for this job.

It's a 23 watt cfl. It's still a baby, only 2 nodes. I just got back from the gym and it smelt funky, definitely had some root rot starting. I guess I shouldn't have changed the res. Anyway I proceeded to sanitize everything and I rinsed the roots down to get the crap off them. Now I have it back in straight r/o water. No nutes. What should I do?

can you get the root zone temps below 70 F? THat would help and water with a mild H2O2 solution. Then treat normally

Right now the temp in water is 68-69. I'll keep on it with ice water bottles. As far as adding nutes again. What do you suggest?

I would feed 1.1 to 1.3 ec . Measure your root zone not the water , your root temp is the important thing

I just got off he phone with Advanced Nutrients support. They said I took all the right steps and to just add some hydrogen peroxide for a day. Then flush again and add nutes. Keeping temps below 70 is what they recommend to prevent pathogens. Keeping this below 70 is a challenge for me. I might swap this over to soil.
