Has anyone tried Hyaluronic eye drops for dry eye syndrome? Seems as if it might help. WebM.D. "Hyaluronic acid is a substance that is naturally present in the human body. It is found in the highest concentrations in fluids in the eyes and joints. The hyaluronic acid that is used as medicine is extracted from rooster combs or made by bacteria in the laboratory. People take hyaluronic acid for various joint disorders, including osteoarthritis. It can be taken by mouth or injected into the affected joint by a healthcare professional. The FDA has approved the use of hyaluronic acid during certain eye surgeries including cataract removal, corneal transplantation, and repair of a detached retina and other eye injuries. It is injected into the eye during the procedure to help replace natural fluids."

We used a Valspar paint in Summer Gray in DS's condo garage. Please note that I do not recall which line of Valspar it was. We used it because DS received a gift certificate for Lowe's. We also used the primer recommended by the paint counter customer service person. The walls were finished about six months before, I believe. Pretty much builder grade everything. The Valspar paint we used was horrible. Spattered, required three coats and still wasn't great coverage-wise. It was thin, messy, smelly, and saggy. I'm nothing like a pro painter, but I get uniformly great results with Farrow and Ball, and I have done fine with certain SW lines, although I dislike the odor. (Oh, and a pro painter who was my GC's sub and used SW exclusively put the wrong color labeled with the right name in a guest house and no one made good on it--so paint mix goofs do happen, even in the expensive stuff). I have used Frazee happily in the past, too. Perhaps because we told the paint guy it was for a condo garage, he recommended the junkiest paint. I don't know. To spend so much time and effort for such poor results . . . I won't go near Valspar again.

I have to say that have I never encountered this problem, ever. And I seldom bother to purchase only organically grown potatoes so I seriously doubt it has anything to do with fertilizers or other chemicals. Hard water, possibly; poor storage conditions possibly. Not aluminum pots - I still use my mom's 60+ y.o. aluminum saucepan for cooking boiled pots for salads or mashed. No black potatoes!! But I would be sort of grossed out if they did turn black after cooking :-( I have trouble with blue or purple potatoes as it is.

Update! So my I scoured other postings and found Mike's advice for adding vinegar to water when watering citrus. Before doing so I tested my water and the differing variations (tap alone, filtered alone, filtered + fertilizer, filtered + fertilizer + vinegar) for pH and hardness. My normal tap is neutral at 7. Fileted through the dehumidifier it is slightly more acidic at 6ish. So I tried one watering of the vinegar and fertilizer, and yes it certainly made my healthy leaves a deeper green, it did not resolve the leaf curl. In fact it got worse. I determined that this was not due to a vitamin deficiency, as no color is leaving the leaves. The leaves start by curling on both sides inward, then hardening from the outside tip inward, until it falls off the tree, felling hard and lacking moisture. I've lost probably 8-10 leaves in the last 2 weeks. I haven't watered in those two weeks. So I dug deep into the gritty mix and found that it was still wet down there, not just moist, but WET! I don't get it, this is what I was trying to avoid by switching over to the gritty mix. I have 10 drainage holes in the bottom of the plastic pot and water drains freely when the tree is watered. I rolled my pot over and gently nudged my tree out to confirm my suspicions - yep some mild root rot!. GRRRR! Needless to say I am disappointed. I had gone from watering the tree once a week with the 9-3-6 fertilizer which gave my tree blossoms, new leaf growth, even tiny fruit production, to depressing leaf drop no better than if I had left the tree in MG potting soil. I have the Gritty mix laying out so it can dry a bit, but I am hesitant to put my tree back into it. Any suggestions from anyone who has been very successful with the gritty mix? Should I add more granite to it? I'm thinking adding more of the Fir bark fines will only hold more moisture in the medium. I'm also thinking about giving the tree's root ball a trimming, not completely bonsai, but to allow some air in between the roots that have grown very close together. I'll post pictures.
