Bubbler Question - How can Nute manufacturer's recommendations be so off?

I've gotten feedback from this and other sites that bubbler systems should ideally be run in the 300 PPM range for early - mid vegetative, with a max in the 600 PPM level at late veg and bloom. However, if you follow directions on Botanicare's nutrients and supplements for hydrogardens, it would put you well over 1000 PPMs, even in early vegetative stages. For example, in a 5 gallon bucket, if you put 1/5 strength in 5 gallons of water (recommendations for 1 gallon of R/O water) it immediately gets you into the 250 ppm range, 2 gallons worth gets you to 500 range, and so on. I've experienced toxicity even at half strength of recommendations.

My question is, how can the manufacturers be so off on their recommended amounts? And what's really crazy is that they even have recommendations for "Agressive" veg and bloom, which kick the nutes up even higher!!!

i think he is serious, don't different plants need different amounts of nutes? I doubt the people send off general instructions for using their product to grow marijuana : )

People bud plants at 1000 ppm.

It all has to with just how big your plant is.

Yeah it is crazy but it all matters on the strain and how ur growing. One time when I grew aeroponics I got the ppm up to 2000 and the plants loved it. You just gotta watch the plants and see how they respond. One of my Jack Herers mother plants is at 650ppm right now in a bubble bucket, and growing about an inch and a half a day!! -------peace
