Diagnostic and treatment help needed please.

Any ideas about what your grow building was used for before you acquired it? Or did you have it built for your operation? Maybe there are some residual chemicals or contaminants affecting your plants. Maybe you could submit a plant for testing and say it’s hemp.
 
Hm, so you already have a control group, great! I assume you measure ppm, ph, etc. regularly. Perhaps you could compare? If there's any difference between the plants at the facilities, especially within the past few days , more investigation is warranted.
 
Been thinking along these lines myself. It was a machine shop for many years. It's a metal building, and when we renovated as a grow facility it was stripped to the shell. Only remaining original material is the foundation, metal beams and sheeting, and the insulation on the ceiling. The insulation is the only porous material. Like most insulated ceilings in metal buildings it is fiberglass with a plastic sheet backing.

I can't think of anything that would have been present in a machine shop that could permeate the insulation and persist in high enough concentrations over time to be a factor. To the best of my knowledge the insulation is dry throughout the facility - we have no roof leaks of any kind.
 
"yes, all parameters are monitored rather meticulously - especially since our first experience with this."

Have you compared the measurements with your "control group"?

Also, how many grows have you successfully completed in this cursed facility?
 
There is a place near me that uses trichloreathane to remove grease from metal, they hang the part to be degreased above it. IF something like that got into the floor (what is the flooring?), thats some bad shit never touch the part yet the grease runs off.
BTW I am not saying that is what it is, just an example I know of.
 
BR2K zero grows completed in this facility. It's brand new, though this is the second set of plants we've attempted to import to this site.
 
Rwise the building was a metal fabrication shop prior to being repurposed to a grow. The floor is concrete, though it has since been sealed and coated in a commercial epoxy flooring compound.
 
OMG again.. take a water sample from last feed and test it in a professional Lab, the run off to.
This as to be sabotage, sure you already have video and sensor security, but my question is, the main water line that enter the facility, where is it? here, we have a cabinet with the main water line and counter, outside the buildings so I guess it can be sabotaged by anyone, Or, the other thing that occurs to me is your Ph controllers, is that a chance of bad calibration, malfunction...
Men Im praying for you

tropa the water line comes into the building underground. I don't see how anyone could sabotage that.

Otherwise, nobody is ever in the building that I don't trust 100%. Everyone working here has a personal financial stake in success.

Yes, media is coco. Ph controllers have been checked and rechecked against both drops and strips. Also, it's only affected about 1/3 of the plants, and all were fed the same nutrients and water. If it was something in the feed mix I'd think it would affect all plants simultaneously.
 
Is your coco from the same manufacturer and as expiration date, is it pre buffered or you guys do it anyways, any chance of mesure run off EC from damage plants and healthy ones
 
What an absolute headache of a mess Serapium. It sounds like you’ve controlled all the variables very precisely. Reading all the previous info, the only “red flag” that pops up in my mind is the fact that this is a new facility. If you’ve grown these clones successfully before in a different building, then there has to be some sort of residual chemical(s) lingering in the building that’s hindering your grow. Just my $.02. I would take one of the infected plants to a different grow space and see how it reacts. That may give you more information as to whether it’s something with the environment.
 
I'm curious too. I hope for two things: 1. Serapium has gotten his/her problem(s) ironed out and 2. We learn the source of the issue.
