Using drops for pH will do in a pinch, but I'd add a good pH pen to your wish listDrops are hard to get accurate readings from. I use an ECO 2, it's fairly cheap but has done me proud.
Again, I've used organic apple cider vinegar to lower pH, but it's short lived compared to products like GH Ph Up and Down. Again, maybe a wish list item
Last on the wish list, IMHO, would be a nute package that allowed for tweaking the P and K without dinking with the N. This will be very important during flowering, when you want to boost the latter and reduce the N uptake
Not trying to bust your chops, Amigo, just sharing what I learned from the folks during my first couple of grows
The youngsters are looking great.... I think Babs has my eyes!
i got the other shultz wich is 2-7-7,should i use it or just go for straight pk,hard to find those and wich one do you use?
as far as i know that best for veggy is 6-2-4 and for flower 1-2-4,and some people likeyourself say we should have absolut zero nitrogen when growth is done.
now,im gonna tell you what i believe.
Brother i know that the chicken your patting is an actual shaaman and not an ordinary chik
,so you have the wisdom of shaaman's 
.just give me a name of pk product.thank you so much brother RR. very much appreciated.
But in that line-up I have one product that is all N, and for example AN Bloom is 1--3-4, and Big Bud comes in at 0-1-3. All the canna lines will tell you "this+this+plus this... the art comes in understanding the analysis of each component, and tailoring it to your needs at the moment
Just like anything, JIMY, as you grow you find things filling your shelf that may or may not ever be used
bbbbbbbbbbbbboooooooyaahhhhh baby. LOLITA it is.
