Paph problems
Hello all, again. My Paphs--sukhakulii, gratrixianum, Magic Lantern, and a few
others just don't seem to be doing well. The leaves, especially the older ones, are pale, yellowish and waxy, and they don't seem to be growing at all. My growing conditions: in my bedroom, days 65-70F, nights 52-55F, about 30-40% relative humidity, some ambient light and about 12-15inches under 4ft. flourescent lights. I try to keep them moist and feed with weak paph fertilizer supplemented with calcium and magnesium. I use RO water the rest of the time. Is it just too cold for them or what? Too much light? I do have a mini phal that is in spike, but has sort of reddish tinge to the outer edges of the leaves and is not a strong looking plant...Thanks for any feedback. Other genera are doing okay. Cattleya skinneri is in full bloom! Karl |

"When in doubt: repot"
That should be somewhere on your list of rules. "Rob Halgren" wrote in message ... Jbkkhawk wrote: Hello all, again.

After repotting, I might also suggest moving them right up under the
lights, and trying to get the daytime temp up 5deg or so. Perhaps enclosing the growing area would increase the daytemp (because of the lights) and make it easier to raise the humidity as well. |

All these suggestions are sound. Check www.ladyslipper.com. Antec has lots
of good cultural articles. If you're going to keep them that cool, you might let them dry out a bit more before watering.

In addition to the great suggestions already mentioned, I'd suggest
modifying the feeding/watering regimen a bit: using straight RO water can lead to really extreme pH levels, which can affect the availability of nutrients to the plants. Personally, I feed a weak solution of known TDS and pH at every watering. -- Ray Barkalow First Rays Orchids http://www.firstrays.com Secure Online Ordering & Lots of Free Info!

I have an RO water / pH question - I'm watering w/ "distilled" water from
the dehumidifier that keeps the rest of the house safe from the humidity that leaks out from my loosely enclosed table. I've noticed some root tip burn and some chlorosis (I'm sure that's spelled wrong - lack of green in new leaves) which I know can be caused by a multitude of issues from too much light to not enough iron but I thot it might be pH related so I went out and bought an aquariam pH test kit. The water before fert reads just about neutral (7). after adding fert, pro-tekit, superthrive it's a bit basic, maybe 7.2 or 7.3 which I don't think should be an issue... but could something else be going on in the pot? How / should / could I check it? The other interesting thing is that the dissolved salts in the "distilled" water reads more than the water straight out of the tap - 40 ppm vs 33 ppm here in Seattle.

What is in the Seattle water that you are trying to escape? I ask the same. The
water up here is so wondxerful compared to Southern CA.

Not really trying to escape anything except chlorine. It's more that the
dehumidifier is "making" water so I might as well use it. I remember when I was a kid, my mother would use it in her iron thinking it was essentially distilled or pure water. I figured the same but was suprised when it read higher on the TDS meter than the tap water. And yes, we're blessed here in Seattle with great water! In the greenhouse, I simply use a hozon thingy to add fert to the tap water. "Clare Sleeter" wrote in message ... What is in the Seattle water that you are trying to escape? I ask the same.

This is pure speculation, but as you're condensing water vapor from ambient
air, aren't you possibly getting some of the other airborne species along with it? -- Ray Barkalow First Rays Orchids http://www.firstrays.com Secure Online Ordering & Lots of Free Info!

Hi Karl, From what you describe, sounds just like some of mine! I found
Mealies down at the base of the plants!!! Also, what potting media did you use? I used some Coco Husk Chips, didn't know that the stuff needs to be soaked & the leaves were light & turning brown fast! Cheers Wendy "Jbkkhawk" wrote in message ... | Hello all, again.

We have pretty basic water here in KC. Nearly pH 9. No problem with salts if
I flush well when watering. I used bottled distilled for my brachys though. For all else, I just lower the pH of the tap water with apple cider vinegar, a natural acid with some bonus micronutrients as well. The phals love it.

Thanks (Ray too). I will cease and desist. Watered this AM with tap water
after dumping about 10 gallons of that other stuff. Now I'm wondering if I should repot everything? I think I won't... "Susan Erickson" wrote in message ...
