And whoa whaoa whoa… wait a minute folks… I just studied this pH cannabis soil chart. And according to this chart, Phosphorous and Calcium starts to drop off below 6.3pH (we’re talking soil chart, it’s different for Coco) Well, maybe my pH doesn’t check out like I initially thought it did. Grabbing some Limestone tomorrow morning from Home Depot to get that soil up to at least 6.5. And will measure the other pots with the healthy specimens just to make sure, wondering if they’re at 6.3 and below too. If they are then I’ll drop the Limestone idea for a minute. If they’re not … racing to Home Depot
Dolomite has a neutral pH of approximately 7.0, meaning it cannot raise pH levels beyond 7.0. Therefore, it’s the best and safest way to make sure your soil remains pH-stable for a few months, and plants grow optimally.
Update:
And we’re back on the right track, the ladies are responding well to the Dolomite Limestone, all my pots are at a low pH at the moment (not favorable) so the addition of the Dolomite Limestone could not have come quick enough. As far as Soil grows go, a pH lower than 6.3 will be the beginnings of problems. Phosphorus, Calcium, Magnesium, and Molybdenum will not be as readily available at a low pH in soil. Dolomite Limestone will naturally bring the pH up adding Calcium and Magnesium at the same time to your soil. In a few weeks my soil should be back to optimal levels, (hopefully at the 6.5 mark) Wow…what a journey…learned a lot this week.
I’m just curious as to what type of nutrients the plant is looking for when it drops it to 5.8pH? According to the soil chart, there’s not that much there. Does anyone have a clue as to what that might be?
