PH level and how to change

Grow Support

new guy. I just got my ph meter and the meter says my soil is off the chart alkaline. My plants are three weeks old and in varying stages of success. What is a good ph level for weed and what is the quickest , easiest, and most realistic way of getting the soil to the correct ph?

Thanks, Mike

Yeah, I was looking for that template. In soil I believe your range should be between 6.0 and 7.0 pH. Your girls absorb different nutrients at their roots better at different levels, but 6.5 pH is usually the sweet spot. Good luck.

6.5 is definitely where u want ur pH level if ur in soil. I would just make sure u pH any water or food ur gonna give her at 6.5, eventually it’ll get there

I recently seen a meter that’s designed to measure ph in soil. One that actually works, but when I saw question talking about ph level in soil I had a suspicion that maybe this was one of the cheaper soil probes.

Most soils needs a ph of 6.5 So Always ph water going in to 6.5 You need a Actual ph meter, not a probe style that doesn’t have a digital readout.

Okay, here goes. Pardon my ignorance . I have never grown a living plant.

  1. Indoor grow.
  2. Off the top of my head I don’t remember the name of the company.
    3.Autofem
  3. Simple tap water- the meter reads it at 8.0
  4. my feed solution… is 8.0. I don’t know what TDS/EC is.
    6.Soil.
  5. 20-20-20
    8.Grow LED…4, one for each plant. 6" distance, no heat.
  6. Temp just adjusted to 70.0,
  7. RH is 50-53
  8. Humidifier
  9. Yes, 4"
  10. Don’t understand CO2 I know what CO2 is just not in this relationship.
  11. This is my first grow. I have four plant, all will be three weeks old tomorrow. One is 6" tall, one is 5" and the other two are about 3". Other than some slight leaf browning on two of they, they seem…okay.
  12. As inexpensive as possible but I do want success. I have to plans to mass grow, this is to help my daughter keep her prescription weed costs down.
  13. Next grow may be hydro.

I am beginning to suspect that my meter is the culprit. I just measured my bottle of distilled water which measures 8.0

No need for apologies, we are all here to help. I realize it’s easy to get overwhelmed, when you have 4 people answering your question and also asking you questions. :+1: I just wanted to say that ph is important growing cannabis so when you get a chance let us know what type of meter you have.

I do not believe miracle grow is cannabis friendly. asking questions is getting knowledge, never feel afraid to ask questions, this is what this place is for and this community is amazing

OK I’m sure I’m not going to be the only one, miracle gro can be problematic for cannabis. Time released nutrients will cause your plants to get nutrients when they don’t need them.

It can also cause ph swings, also not good.
