Do Your Nutes Make Your Ph Go Down Or Up?

[scottonfire]

To me, it makes good sense to pH down or up FIRST to get the right environment to then add your nutrients. I believe that would maximize nutrient uptake. But I can't remember if nutes decrease pH or not so maybe this is why most people blast their feed with acid/base after adding nutes.

My pH goes down quite a bit after adding nutes

pH goes down after adding nutrients. Add nutrients first, test pH then adjust.

Always adjust ph after adding your nutes. Different imputs have different effects Silica will make it go up, acids will make it go down.

It depends on what type of nutrients you're using.Most use NPK lines and ph'ing after doesn't hurt anything.
If using something organic that contains microbial life then you have to be more careful as large ph swings can kill beneficial microbes.I use nectar which is calcium based nutrient and the bonemeal from the herculean harvest drops the ph drastically so I usually add herculean to my water first then bring the ph up before adding the rest of my nutes.

Depends what your adding. If it’s acidic ph will go down if it’s alkaline ph will go up. Usually nutes should drop ph just a bit. To end on the slightly acidic side. I mean 3 part nute mixes.
