Hey all...

I need a recommendation for a good all-around fertilizer for my orchids. The one I've been using was highly recommended by the high-end nursery I live close to, but upon looking at the label, I now see that 95% of the nitrogen in it comes from Urea, and I have read that Urea is bad for orchids.

Also, I have recently discovered that some of my orchids need calcium, and this "professional formula" contains none.

Could anyone direct me to a more well-rounded fertilizer for orchids? They seem to like the high-nitrogen, but I'd prefer it didn't come from Urea (although I don't quite understand the chemistry behind this), and I'd like it to have some other useful stuff like calcium and perhaps seaweed extract...unless seaweed extract is something I need to buy separately.

Thanks, friends!
