Paph problems
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! "Jbkkhawk" wrote in message ... 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 |
