Ray, I appreciate your input and will be attending to water/fertilizer with more understanding. I have ordered a EO,TDS and PH (I have a TDS meter, but,) the deal included another TDS meter as part of the price (its only money). I will be conducting a 'pour thru test' as soon as I get the meters. I am extremely happy to have joined the orchid board, I find that the information I've been finding before is 'NOT' very useful, because one article says one thing and another article on the same subject will read completely opposite. I should have joined Orchid Board 4yrs ago when I started to become more interested in Orchids. I fell I have to introduce myself properly: I am a 'service connected'(100% disabled) Veteran with PTSD and I have been 'socially' separated from society for 57yrs, I've been addressing my Traumas for about 10yrs in group therapy at the VA. I didn't realize that Orchids would be helping me with my 'problems', even better that going to Orchid shows (which I had a problem going to) would be helping me as much as it seem to be doing. I am not looking for 'sympathy' from any one, I just wanted to 'thank all of you for your help and comradery. Thank you all again, Zoren......
