150ppm is nothing, is that right? is this hydro, soil?
No need, just wanted to understand. I am puzzled. My tap water alone is over 150ppm. Usually my nutes are running at 900-1100. What brand of nutes are you using?
Is it time to flush? The trichomes are ~5-8% clear, 90% milky and leftover are turning amber.
Thank you!
What does air input have to do with it?We're in the hydro thread but yeah, I will add to my topic :D
150 ppm is nothing but I have a good air input so I have to lower my ppm. Can't go higher than 450 else I see burned tips.

You don't have enough buffer to hold your ph stable.
Why are you flushing in hydro? It makes no sense? Flushing is only beneficial in soil to lower nutrient concentrations of the soil. In hydro just lower them. Nothing will pull excess nutrients from the plants if they have been over fed.
Plants still need nutrients to develop bud they just require a lot less at the end of flowering. Starving your plants is not going to help.
Feeding properly throughout the grow and not over feeding is the key. Robbing them of nutrients in the end won't really fix it.
Cutting back on nutrients makes sense but flushing in hydro makes no sense.
I'm sure people will disagree.
Why is it needed?My other system is running fine at 100 and 5.9, no ph drop... That's why I'm kinda confused.
As for the flush in hydro, you need one but only 2-3 days are "required".
News to me.... I don't buy it I cannot see any reason air would affect nutrient solution strength. But I'll see if I can't find their reasoning behind it.The more air input, the less ppm you need. (Taken from Cultured solutions website)

I see what you are getting at but let me kind of explain the science behind it. Often times companies twist things to suit there marketing needs.As there is more oxygen in the water, the nutrients are more accessible to the roots, so lower ppm is required.
And, I tried to follow the schedule... I'm burning them once I pass the 450ppm mark.
As for the calmag, I'm in the end of flowering, I won't add only ca/mg nutrients... I just raised the ppm solution, I will see how much it will be tomorrow... It should reach 180-200ppm, waiting for the topoff to drip =)
The starving point is a good point... I was wondering how much is "starving"...
So in soil you can't just change the nutrient concentrations at will like hydro. So in soil they flush to lower the nutrient concentrations and in hydro all we need to do is lower themSo in soil, you need to flush but not in hydro, can I understand your idea behind this claim? Everywhere they suggest to flush even in hydro... I could use the same pattern, in soil, if you don't overfeed, no need to flush because the plant only took what it needed and the leftover are still in the soil.
tap water and GH trio.I'm using cultured solutions and RO water. You?
