I did some quick googling...and it appears to be a Fusarium brought on by thrips feeding on the new flush- and you mentioned it just flushed too- causing the spots and chewed, dried, look. What to spray I cant tell you..there's a lot of mentions of various brands. Good luck.

The only difference I can see with older wood flooring is that a lot of it seems to be clear or high grade and thus it was likely cut from the outer portion of a tree as opposed to the center. Wood from the center of a tree is called juvenile wood and is formed during the first 5-25 years of growth. It tends to have less dimensional stability and lower density (contrary to Lowe's "center cut is better" lumber ads). So it quite possible with some of today's flooring (especially strip) that you are seeing softer juvenile wood from the center of the tree. That said, many hardwood sawmills do not cut the center of a tree for any grade lumber and instead utilize it for pallet cants or railroad ties. Softwood sawmills cut studs right down to the pith, much to the dismay of today's framing carpenter. Commercial sawmills sell the higher grades of lumber (FAS, #1 Common) to cabinet plants and distribution yards while the lower grades (#2, #3) go to the large commercial flooring plants. Through optimization, the flooring plants can make select or #1 Common grades of 2" wide flooring from low grade lumber. What I posted earlier about density is true if one is comparing apples to apples. A tight growth-ring piece of oak lumber from the non-juvenile portion of a 150 year old tree has LOWER density than a second growth piece of similar lumber from a 70 year old oak tree. The explanation is simple. Slower growth results in a higher proportion of lower density earlywood cells (the annual rings you see). With faster growth, you get more thick walled latewood cells and the same amount of earlywood cells which remains constant. For anyone interested in learning about wood and wood properties, there are plenty of good resources available. My source is "Forest Products and Wood Science" by John Haygreen and Jim Bowyer.

I researched this product for months trying to decide if it was the way to go. I have been able to ascertain (to my satisfaction anyway) that Konecto and the Allure (HD) product are by the same manufacturer. If you go to Home Depot and ask to rent the installation video (which BTW is really nothing more than the sales pitch for the product) you will see that the scenes in the video are identical for the most part to the scenes in the Konecto video you can see online. Same set, same floor, same actors.... We are nearing completion of a 500 sq. install of the HD grade and let me tell you it ain't as easy as they portray it to be. *IF* you are working with a sqaure or rectangular room of the right width and length it isn't too bad. However, our rooms sort of meandered from one to another with hallways, cabinets, differing length stem walls and differing room widths...Frankly, in this application it was a real PITA to get this stuff laid. I would strongly suggest anyone using this product in odd shaped rooms where continuity is important to plan on spending considerable time in planning. It can be done but you can end up in a pickle if you don't plan the entire project from the first strip to the last. We laid this product over plywood sub floor that two out of three conventional vinyl installers said they would lay vinyl over. However, the bids for laying sheet vinyl came in at between $3000 and $4500 for mid-grade vinyl. Even with a good floor you will want it smooth or the product *WILL* telegraph major imperfections. $995 for the Allure product was a much more affordable option for us. However, it was not a walk in the park and it a lot of time spent on you knees and scratching you head trying to figure out how to stagger joints using the 1/3, 2/3 cuts when working with 3 foot strip lengths in a 15.5 foot room. (can't be done as far as we can tell unless you manufacture your own splines)...Which while I am thinking of it is a suggestion I would make to anyone planning on using this product. Learn how to make a spline in the event you need to reverse lay or shorten a full strip to avoid ending up with a itty bitty fill piece. As to warranty- I would buy the product on the internet. Generally, warranties aren't worth the paper they are written on... And, I can tell you from personal experience that offering me all of my money back if the product fails wouldn't begin to cover the amount of work it has taken to get this floor down! Since I seem to be writing a book on the product I will add that I thought the Allure product looked cheap and ugly when we purchased it. Much to my surprise that phony looking grain pattern looks really, really beautiful when you get it on the floor. Distance improves this product! One last hint for the Allure product...Don't believe Home Depot when they say there isn't a variance in color. They repeatedly assured as that there was no need for matching lot numbers and they lied. Luckily, I didn't trust them so I pulled product from each lot and intermixed it. You can still see patchy color variances but it actually enhanced the look to appear even more like a real wood floor. And yes, it is a much quieter floor than laminates and even the existing vinyl that it is being laid over. Elise

If my kid smoked pot occasionally, I would not be too concerned, but not sure why this devolved into the pros and cons of pot, since the OP posted that it was much more than that!! Smoking pot, hanging out with a controlling boyfriend, and not being very motivated in school could be a temporary bad spell as a person adjusts to being on their own, or it could be signs of depression and a downward spiral. I teach college, and that combo would indicate depression to me. Each sign on their own, probably not, but all together, perhaps. What to do about it is another story. I have a friend who had a son who was in an abusive and inappropriate relationship for years, and also had trouble finishing college. It took him a long time. They kept communication open, had to stomach a lot of heartache as he made bad choices and suffered the consequences, had to set clear boundaries, tried to get him any help he would accept and use. He kicked around for quite a while but did graduate and eventually got out of the relationship. Some kids just take a little more time than others, their path is not as straight forward. Try to accept that this may be a more difficult path for your child, and steel yourself for being there however you can. There may be no quick fix, it may be a case for stoicism. But keep communicating and keep looking for openings for helpful suggestions, while keeping boundary issues and realism in mind. Kind of a middle road that is difficult to follow. Oh, another one of my students went through almost this exact thing. She eventually dropped out of school for a while, but I got a nice note from her several years later that she had graduated from another school that she transferred to and got a job. So try and keep that perspective in mind, there is not always one ideal path that all kids need to go on, some take detours but get there in the end. They go through a rough patch, but find their way out!
