Water in Columbus, Ohio is very hard and alkline. For the longest time I was using tap water but my plants were developjng nutrient deficiencies left and right and my orchids had leaves covered in calcium deposits. So,I started adjusting my ph.
I use PH down products to get the overal ph to a 6.o. Then, the addition of fertilizer will get the ph to drop a little to 5.8.
Since I haved started this new water regime, my orchids are putting out multiple growths per orchid and numerous more flower spikes.
