Control de pH (principiante)
BENY_TRUBYstarted grow question 3y ago
I have some autoflowering plants growing that I'm watering with a pH of about 7.5 + root stimulant, and I'm going to start using organic fertilizer for grow. I use organic soil, can anyone tell me if it's necessary to use any pH adjuster in my case?

PH 7.5 is high, but if you add any nutrients to it, it'll quickly drop. As someone as said already, "living soil" doesn't require too much effort with regards to PH management, but if you just have "Plant Magic" organic soil or whatever out a bag, it's still going to eventually push the PH too high.
If you can use rain water then that will lower the PH. If you use a dehumidifier, the water it pulls out the air will be lower PH as well. When you use nutrients this will also bring the PH down, as I said, so all in all those cases you're fine. But if you're just straight watering for the next few weeks, you might want to invest in a small bottle of PH down - a little goes a LONG way with that stuff so you only need a droplet in a huge bucket of water.

I advise you to acidify the solution a little. the ideal range is between 5.5 and 6.5. to acidify if you don't have any ph corrector you can use drops of lemon juice to add to the water, then test the solution with a ph tester. you can use this solution for a few days, while you buy a ph down. lemon juice kills both bad and good bacteria in the soil so it is not recommended to use it for long periods of time.

When in living soil, pH doesn't matter near as much as people like to think.

pH helps the plant absorb nutrients in mineral cultivation. Mycorrhizae do the same job in organic cultivation. So it's not that important. It's more important to support the life of the soil.

The soil can tolerate a higher pH value when it is fertilized organically. However, it doesn't hurt to correct the pH value. What's important is that the soil life remains active when you fertilize organically. This means it's more important that the water, for example, is chlorine-free, the soil has the right temperature, etc.

Yes ph is extremely important. The dome is not needed once ot opens up. It can encourage mold and rot if on too long. Anyway your ph controls absorption ability of roots. .1 is a big difference for a plant. Should also test run off to get reading of soil ph

Take the humidity dome off, you don't need it once she's sprouted & ideally get your pH down to between 6.2 to 6.5.
Goodluck
