Paphiopedilum Brown Spots and Darking of Leaves

[KristofferNgo]

About the Paph Ciliolare, I think that's what I'm thinking too... it's just losing old growth...

On the Paph. Philippinense, the spots look like freckles... it has a lot of it.. it's quite small, but I did take close-up pictures.. the spots are not at the center of the pic, but you can see them on the leaves... The medium looks dry, but when you dig a little deeper, the medium is moist

By the way, I read one of your threads about Humic Acid... do you think it's a good idea to use both Humic Acid and Fulvic Acid together with the fertilizer? Of course, I won't go overboard with them.

Yes, I think it's safe, because my experience tells me they do little to nothing.

They're supposed to enhance nutrient uptake, and that may be advantageous in fast-growing plants, but it seems to have very little benefit - if at all - for slow-growing plants like orchids.
