Lemon juice bring that baby down?

Thanks
Lemon juice works in a pinch, as does white vinegar. Not good long-term tho.

There are many "quick and easy fixes" to a myriad of problems. (like the lemon juice or vinegar for bringing water ph down) Keep in mind that these should really be used like band aids, and not as the cure.

The flower nutes I use (Fox Farms Tiger Bloom - 3.1 ph out of the bottle) lower the water ph by .1 or so. My veg nutes don't even change it that much. (Fox Farms Big Bloom - 3.6 ph)
If you start off with water at about 6.8 to 6.9 ph, you should be fine.

I did mention the run-off problem, right...? When yellowish and bluish doesn't really mean 6.8ish...edjumicated guestimating comes into play.

This is the biggest problem with the aquarium test kits. Don't get me wrong, I used those kits for years. After the first time tho, I quit trying to determine the run-off ph. So, not knowing the run-off ph, I flushed every few weeks to alleviate any possible salt build-ups or ph problems. (peat based soil mix)
Now that I have a pen, I still havn't broken myself of doing the flushes, but at least now it's not as often, and not out of a panic wondering about ph fluctuations.

Making your grow easy to care for, and sustainable is the goal. You'll soon want to invest in the proper tools and supplies. Soil, nutes, ph down (agricultural grade phosphoric acid), a ph pen and calibrating solution are a few to look into.
