Interesting topic as I recently switched from nitric to phosphoric
and decided to blend the two for the transition.
Started at 1:1 and tapered off the nitric after a couple weeks to 100% phosphoric with no ill effect.
In my grow the nitric had a slight difference in flowering fan leaves
turning yellow slower, and perhaps inhibiting flower production,
throwing off established finishing time by days with plants I have
flowered many times.
In a perfect grow perhaps using nitric in veg and phosphoric in bloom would be the way to go.
But I don't currently see the need to be that specific, however, if there is quantitative
analysis to bolster the use of both in the way I describe, then I, perhaps,
would make the adjustment.
Good answers from all there, thanks. Yeah I may be wrong but I have a thought a lot of the big professional indoor food producers often you Sulfuric acid too, It would certainly make sense for flavor and smell augmentation.
As long as it don't fuck my Rez up mixing 2 acids, then it's Thunderbirds are go.
