I like to keep my spaces around 1.22
just needed to stop by and show Seamaiden that im back on track, the charts and advice helped out alot...

thanx for the help...

Hell yeah @click80... once you get a handle on vpd, it's so much easier to understand how to create an excellent environment. Thanks for sharing the input
I apologize, I wasn't thinking when I posted this here & I figured out what was the issue with that plant you & caregiver ken helped me on. I'll start another thread since it's not the same plant & thanks for the quick response Sea.Eeehh... I know that I tried to help caregiverken make a diagnosis in this thread, but between that, the other charts others are posting and now this, I think you might be better served simply starting a thread on your problem plant. Otherwise there's a good chance your post is just going to get lost in what's becoming a thread of several pages.
Besides, Sea needs to see the whole plant, along with more information. Soil or soilless (specific media is most helpful)? How much of organic nutes? What are the nutes? Etc, etc, etc.
ok so a few chemistry questions.?
given these facts...
ammonium toxicity is more prevalent in acidic soils
nitrate toxicity is more prevalent in alkaline soils
if ammonium is NH4NO3 and ammonia is NH3 and nitrate is NO3
what enters the plant?
by what mechanism?
at what point does ammonium nitrate separate into ammonia, nitrate, nitric acid and one of several alkali metalic nitrates
reason for this...when i brew PSG (peruvian seabird guano) the odor changes dependent upon how long its been brewing and at times there is such a strong ammonia smell that it really makes me question when to use it.
another chemistry question, on the charts above on post #90 in soil Ca and Mg are locked out below 6.4. What do they bond with and become?
That's actually misleading. Calcium and Magnesium are Base forming ions, they become less and less available dropping from PH of 7 to 4. As the soil drops in PH, they become insoluble. In a solution, I think you would call it precipitate. At very low PH, certain elements like Aluminum and Iron become toxic...that would otherwise be helpful. Calcium and Magnesium can affect Phosphorous when the PH becomes too high(for example 7.5)..Phosphorous ions react with Cal and Mag to form less soluble compounds.another chemistry question, on the charts above on post #90 in soil Ca and Mg are locked out below 6.4. What do they bond with and become?
