I am looking for someone to help me better understand how the MJ plants absorb their nutrients.

I have been an avid Bermuda grass grower (lawn), and have learned that ammonium nitrate added to my lawn will take about 4 days to kick in, with full results in about 7 to 8 days.

Is our favorite grass's rate about the same? How long does it take for an average 24" or so female plant to show the nutes she's been given?

Thanks

What nutes did you give it. Its usually about the same sometimes earlier it depends on the nute. Nitrogen for example should be seen in 2-3 days. But some nutrients have trouble being absorbed by the roots, like iron Fe, so it can take 7 days or a more. Foliar feeding though is crazy, overnight, no matter what it is, but be careful of burns. Also depending on how hot it is and how much you water the faster nutes will be absorbed. When its hat and the plant is sucking up water and transpire water quickly the flow of water acts like a pump. And nute burn pops us in a couple of hour, and will progress for a day if its weak. Or progress for 2-3 days if its bad. Lamp

here is some useful info on metabolism although doesnt answer ur question about photo

Where?

lol

Im confused too, his title was a little misleading "photosynthesis rate". That would imply how long it takes under a certain amount of lumens to make G3P which is the sugar plants use. Which of course varies depending on nutes, amount of water, co2, and oxygen, oh and especially light cycle. So the answer to just the title is slower than a cactus or faster than ragweed.

But in the actual text box the question was the rate of absorbtion of nutes through the roots epidermis up into the xylem and throughout the leaves.
