What are the signs of fertilizer burn in orchids, and how can I prevent it?
In my pursuit of nurturing beautiful orchids, I've encountered what seems to be fertilizer burn, and it's concerning! My hydroponic setup has been using a specific orchid fertilizer, but I've noticed browning leaf tips and a few wilting flowers. I suspect I might have over-fertilized. I've tried diluting the fertilizer, but I'm still unsure of the precise concentration that is safe. What are the signs I should look for to confirm fertilizer burn, and how can I adjust my feeding regimen to avoid this in the future? Any preventative measures to take would be invaluable!
