This is a discussion on DYNA-GRO K-L-N, Pro-TeKt and superthrive within the General Orchid Culture forums, part of the Orchid Culture category; ...
I posted about how to encourage new roots and growths and everybody recomended me superthrive and K-L-N for it. So I went ahead and bought them, when I was reading the K-L-N instructions it mentioned another product, Pro-TeKt and I bought it too.
I´m using a tea spoon of superthrive and 2 tea spoons of K-L-N and Pro-TeKt per gallon, and instead of watering my orchids because I consider that is a waste to water the product, I´m spaying them with this formula, making sure that the media and foliage get complety watered. How many time should I apply it? or is it correct to do it like that? do I have to apply a less dose to healthy plants?
As well I fertilize my orchids with miracle gro single of 24-8-16 formula, the instruction says to use one package in 2 gallons for indoor plants, but cause I think is to concentrated for orchids I use the package for 4 gallons and I fertilize watering it every 2 weeks.
I don't know anything about protekt but combining the other two sounds like way too much rooting hormone IMO. I have used the dynagro at the lowest dose on the product label, once or twice a month, it was enough to stimulate root growth. Water the growing medium (or orchid mount), rather than the leaves.
Orchids are weak feeders; volumetrically, how much fertilizer are you adding per gallon with the packet? When I use Miracle Gro 30-10-10, I use 1/4 to 1/8 teaspoon per gallon.

Pro Tekt is meant for plants to deal with heat and cold stress I have used it and seen a bit of difference nothing significant , it is not really a fertilizer. I tried it as an outside grower in Florida because our summers can be hot, I just noticed more lower leaf yellowing when I used it, you don't have a location posted so if you are growing outside where heat and cold can be a stress for your plants. Catt Mandu is right the other 2 are growth hormones not fertilizers, use 1 or the other.
Pro-teKt is a potassium silicate solution. By itself, you will have a solution that is far to basic for the well-being of the plants.
As the three excellent responders above have implied, your strategy is REALLY overdoing it. If you want to treat your orchids right, drastically reduce the fertilizer concentration and feed more frequently, adding SuperThrive OR K-L-N no more frequently than every 3-4 weeks. Personally, I'd skip the Pro-teKt altogether, but if you're going to use it, treat it as a fertilizer additive, and make sure you don't shift the pH too high.
