Soil ph problems

Hey ppl,

Im currently growing some plants inside that are gonna go outside in the spring. After checking the soil'd ph, I found out it was at 5.8-6.3. I wanna raise it to at least 6.5-6.8. Anyone know any simple remedies to my problem?

How did you test the soil? I'd probably leave it be and adjust the feeding pH. You can always add hydrated or dolomite lime to raise the pH if you feel like you need to.

Powdered Dolomite Lime is the simplest and cheapest. Supplies cal/mag too.

@~$5 for a 40# bag, it's hard to do cheaper.

Just add it to your mix before use. "I" use 2tbl/gallon of mix or 1cup/CuFt of mix.

I assume your talking about the outside soil you are going to plant into. I would go to the dept. of Agriculture web site for your state and find how to have soil samples tested in your state. (Generally the is a county agriculture extension). Follow the procedures for testing for a vegetable garden. They will tell you not only how to adjust the pH but tell you where other deficiencies lay. It is the best way to know exactly what your soil needs.

three good answers. thanks

Why would you want to raise that ph? It's nearly perfect, and will probably creep up slightly throughout the grow unless it's got a lot of peat.

You think so? Everything I read saud that the soil ph should be between 6.5-7 so I figured the plants would grow faster if the ph was dialed in better. But now that you mention it, I probably would get in more trouble trying to fix it than I would be just leaving it.

I'd run with it. 6.0 is perfect in my opinion.

IDK, 6.0 in soil is getting to lockout low for cal and mag.

don't fuck with it! the soil's micro life will adjust pH according to plant needs, so long as it's healthy living soil. yeah, 6.0 is approaching lockout for Ca & Mg but the fungi & microbes will fix it . and there is no ideal pH across the board with cannabis; what is ideal will vary from strain to strain

Ok, but my microherd really appreciates the lime helping them out. LOL

Have the soil tested, don't guess. Its generally only like $15. They will tell you exactly what to do to adjust your soil pH and nutrients.

Ok, I am going to leave the soil alone for now, but I'm pretty sure there is a optimal ph level for cannabis. In jorge cervantes' grower's bible, It clearly shows that 6.5-7 is the most efficient ph level for nutrient uptake in cannabis.
