Shultz Orchid Food

[Ray]

Yes.

I have cut my feeding to no more than 50 ppm N - usually even lower.

No, that would be too weak. You're supposed to put seven drops per about one liter or water. almost 28 drops per gallon. Well, at least that's what the direction says.

I used as directed for Amaryllis and other house plants except for orchids, for which I use about half strength.

there ya go lol. liter. yeah i put in about 7 frops per 1.5 liters to avoid burning them in my heat and use it on the leaves. no negative effects yet

Yeah, with that concentration, there's no burning. I haven't had any leaf tip burn. some orchids have dark, almost black roots on the surface, I'm not sure if that's due to fertilizer or phenol (plant by product)

Interesting, I've always followed your 125ppm N recommendation using the calculator on your website. Maybe I need to adjust.

Do you still flush, I take it NOT, as you say you do this with every watering.

The "Rain Mix" I use in the greenhouse, which is the equivalent of MSU, has a lower mixing rate and Masdyman who sells it in the UK suggests not flushing with the recommended concentration.

I'm thinking I need to adjust my methods as the experts seem to be adjusting theirs.
