Can I fertilize pleurothallids daily

[itilien]

Hello,
My terrarium contains mostly pleurothallids - Pleurothallis, Lepanthes, Trisetella, Stelis and Restrepia. I mist them (heavily) automatically every day and I'm wandering if it's possible to include fertilizer in the water. I suppose that currently when I fertilize on a given day, on the next day most of it is washed out. And I have to keep some schedule. If I include the fertilizer in the water, I won't have to think about it.
Is there any problem with this if the dose is very small? And actually what the dose should be?

I suppose it will be fine if you use like 1/16th of the recommended dose. The main concern is if they are fertilized every day they might get too much fertilizer or minerals might build up on the mounts or moss, pleurothallids are very light feeders in the first place. Probably better to fertilize once a week at 1/4 to 1/8 the recommended dose.

I bet it would be fine if you make it extremely weak. I would probably just fill a separate spray bottle with normal strength and mist them once a week or so by hand.

I mist them from time to time at the moment, but this is not very reliable way, because I forget or postpone, or something else and don't remember where was the last time... Automating the process will be much more convinient. Some people grow these orchids in epyweb or rockwool with constantly running water with some small quantity of fertilizer, but maybe this is OK because they don't dry.
The other option is to include an electromagnetic valves and 2 containers of water - one pure and one with fertilizer.

Just some things to think about:

• Pleurothallids are light feeders
• Much better to under-fertilize than over-fertilize
  (With the former they may grow more slowly, with the latter they may be permanently damaged, it is a lot easier to add more if needed than to deal with fertilizer burn after the fact)
• Orchids can go quite awhile with no fertilizer at all... forgetting on your schedule is not likely to be a problem, eventually you'll remember and do it.
