Soil ph

Aluminum sulphate will instantly lower your soils ph. Can be obtained from most nurseries. Use a little and water through, check the ph. Cheers

Adjusting soil pH is a difficult and long process, it can not be permanently altered quickly. Watering with a pH higher or lower than the soil will not change the actual pH of the soil long term. As long as your soil is not above 7.5 or lower than 5.5, your plant will not suffer any great difficulties. I spent the first 10 years of growing trying to get everything exactly "right" and discovered as long as you don't do anything extreme, it does not matter greatly. Since then and for the last 25+ years, I never check the pH of my soil, but I do not do anything extreme either, like using fresh manure or too much of any one ingredient in my soil mix. I often wonder how cannabis survived for Millenia in the wild, growing so happily without human intervention or having every aspect of their lives perfectly "on point"! Cannabis is a tough and remarkably resilient plant and not the delicate "Princess Perfect" plant some people make her out to be. A few degrees here or there or a few points pH up or down will not make diddly squat difference for the average home grower. Nothing is ever perfect and trying to control the grow down to the fiftieth decimal point is ridiculous. Growing is about fun, not a competition in perfectness. Besides, does it matter if your buds have 21.358% THC and not 21.794%?? There are pH meters, test strips and little test kits, but when growing in soil, it really doesn't matter that much, as long as it is not extreme, but if you bought a commercial type of potting mix, all should be just fine with no need to stress about pH. Often, trying to do a quick fix to an imagined problem can lead to bigger problems than if nothing had been done at all. As long as your plant is growing well, don't try and fix something that ain't broke! Tap water for human consumption is fine too, there is no need to buy chemicals to treat it, these chemicals will do more harm than good to your soils' microbial life, and it is this microbial life which is more important than one or two points of pH. Just go with the flow, and as long as you don't add too much of any one thing or add extreme nutrients, your plant will grow perfectly fine. Hope this helps,........... Organoman.

Hi your soil ph range should be 6 to 7. When you water you should always aim for 20% runoff. When you get the runoff if you catch the latter part of it you can test the ph and that will be roughly what your soil is. If you been feeding with ph above 7 then you will want to flush the plants with ph6 if you been watering with a ph less then 6 then flush with ph 7.
