@Greenleaf Nutrients:
Is MegaCrop so well chelated and formulated that no pH adjustment is actually needed if starting with low ppm water (and adding minimal supplements)? For ex., for multiple indoor grows (coco/perlite) using 2-part MegaCrop I have been treating it just like Adv. Nutr. pH Perfect. That is, using RO water I don't ever bother to measure, much less adjust, the pH or ppm. And I get very good results following your feeding recommendations. Am I simply an outlier, incredibly lucky, to get away with not adjusting pH?
Similarly, what is your view of 'pre-buffering water or not when using MegaCrop? Is mixing MegaCrop into 0 ppm water good or bad? Some growers, particularly those with reservoirs (vs. feeding fresh mixed nutes), pre-buffer their RO or other very low ppm water, such as add cal-mag or tap water before mixing in any nutes. This is seen as needed to "stabilize" the pH level, neutralize or prevent CO2 absorption that causes mixed nutes' pH to vary more over time in reservoirs. Am I correct that MegaCrop itself well "stabilizes" or buffers the water, and users feeding freshly mixed nutes don't need to or even shouldn't pre-buffer their starting RO water? What about those concerned with long term reservoir pH stability?

Hello!
MegaCrop has good chelation and stability, although it is not highly buffered with buffering agents, and in most cases should be pretty solid without adjusting or checking pH, assuming your starting condition water and media are fine. You could maybe check it 1 time after a few days, and see if the pH stability is within your acceptable range, and if so then you probably don't need to pay attention to it at all ever.
The ultimate indicator of course is the results of your plants. IF they are healthy, and producing up to expectations, then everything should be going well, and you also probably don't need to investigate pH.
I don't have an opinion on pre-buffering. Mega Crop can be used with 0ppm water, as it does have a significant amount of Calcium and Magnesium. That being said, depending on what type of environment you are growing in, there may be scenarios where extra cal/mag might be needed. So I wouldn't be able to say for every setup if this is the case or not. With RO water buffering likely isn't necessary. Long term the only thing that would effect reservoir stability is microbes/bacteria.

My own personal experience is very little pH adjusting needed. That's with using the 2 part formula. When I mix up around 400ppm of part A in my reservoir, I usually don't need to adjust the initial pH. After a few days of flooding, I may see my pH increase slightly, but it's usually still in range.
I've used MegaCrop both with RO and low tap, no problem adding the nutes right in. I actually add my cal mag after I've mixed in the MegaCrop to my desired ppm.
MegaCrop has been my go-to for a few years now. Used to use gen hydro primarily, and pH adjusting/frequent checks was always part of the job. I can't see myself going back to that now lol
