Hi
@StealthAlien
Tap water is usually around 7-7.8 PH. fertilizers tend to lower the PH, you can apply the nutes normally. good luck mate 👍

At this point prob ok do you know what PH your water runs? Mine runs between 7.2-6.8 so I kind of know how much PH down to add (almost said up constantly doing that). You will need a way to test soon though even the dyes would do well enough.

PK13/14 or Coconut water?
I am getting ready to give the girls a blast of PK. They are all going into week 5 of flower soon. Please see my diary. Should I give CANNA PK13/14, or can I achieve similar results by adding coconut water to my bat tea? Thanks The Mac

Ph of biobizz solution
My tap water is usually at 7 / 7.3 PH and I usually drop it to 6.3 / 6.5. Today when I did the mixture of biobizz nutes, the PH dropped to 4 or less. What should I do? I have read to not mess with the ph of organic solutions. I’m using biobizz light mix soil

Liście górne
Hej. Czy ktoś mi może pomóc? Nie wiem czy to normalne że moje liście wyglądają tak. Co to może być? Za mało wody? Może naturalne podczas kwitnienia że liście się zmieniają. Jest tak w 4 donicach z 8. Może zbyt mocne światło przy górze? A może poprostu deficyt lub nadmiar.

Watering too much at once vs runoff?
‚Watering when soil is 2,5 cm dry‘:I read the soil should never be ‚swamp‘ wet after watering, yet I also read that the run off needs to be tested regularly - but watering till water runs off does make the soil muddy. Can there be too much water at once if the soil Is dry on top?

Low EC in Runoff
If the EC levels of the runoff are consistently lower than what I'm putting in, do I need to raise the EC levels? I've read that this means my plants are feeding well and can do with more, but I wanted to make sure first. Thanks.

When changing the weekly water, do you refill the basin with regular, then add a 1/4 cup.of water with the grow formula? Or, do you fill it all the way with the grow formula water? It's says to top off with regular water between changes, but nothing about the refill.

Well water
I live in the country and have well water, PH level is 8, instead of trucking in water for the humidifier do you think it would be ok to use just in the humidifier

Outdoor Hempy Bucket fertilizer use?
Added perlite and clay mix to a 10L outdoor hempy bucket, with Skunky Lady on top. Curious about hydroponics fertilizer use outdoors, should it be added early or wait for some growth when the roots hit the reservoir? Seems like it would be wasted if I add it early on....

Bad ph water, it bounces like a pogo stick
My city water supply sucks. The ph rises and falls in such a wide range that it is difficult to keep up to what it needs to level out the ph. I have seen 5.8 up to 8.9 just in the last month. Is there a cheaper method than using the standard PH down?
