It's just $20 if they don't check for N.
I can't say I have used them, as I'm in the UK. I'm paying £30 ($37) for water analysis though. These advertised prices look right to me. The $37 includes them sending me sterile collection bottles, and printed results. Soil sampling was a similar price, but I don't quite remember what. I could tell them what I was growing, and what level of success I wanted. Then their computer would tell me how much of what amendments I should use. This doesn't mean they know anything about growing though. They might see a lot of results, but they are lab technicians. Running a lab is a very different skill set.
Most of the time, it's leaves from the top that are 2-3" long of interest. The actively expanding ones. Made of that weeks feed, with no longer term accumulation. Picking suspect one's obviously tilts your results, towards results of suspect looking leaves. This is why even a lab guy that happens to also know plants, still doesn't really know your crop. Though what they say can still be of interest.
Your RO filter sounds good. Removal of boron from water is difficult, and one of the main challenges of desalination plants. Often they will increase the pH before filtration, to encourage the boron to form a larger ionic compound that the filters are better with. Then 75-90% removal is possible. I'm not an expert on this, I just know it's a weakness of most filters. I'm not sure how boric acid of a meaningful level would effect EC, or how the acid is related to Boron. I just have a rough sketch of an idea, but recognise the weakness of RO filters, in this area.
A quick google finds half our use of boron, is in things like fibreglass. It has a fibre like appearance, so is in structural plastics. So both your Mn and B could be from the system. Tanks/trays/pipes. We seem to get most problems from pipes, as it's softer, I guess. These problems usually effect the mass balance guys, who don't want to do tank changes. It's actually what keeps me away from such systems. I have enough problems
Ward Lab are well known. Soon only approved labs will be allowed to do cannabinoid testing for commercial reasons. I expect Ward will be on the allowed list. Meaning tighter control of the methods used in testing, and less tollerance towards getting it wrong. Or it's bye bye licence. That should make cannabinoid testing worthwhile in the future. Right now, it's just paying to be lied to.
