RQS Bubble Kush Autoflower Grow 🧡

Lowering soil PH is a bit more tricky. You can do it with additives you add into the water like PH down be it from any acids in liquid form. Or you can do it from a amendment perspective by adding in Sulfur compounds that when broken down by microbes release Sulfuric acid that also lowers the PH without having the need to touch the water. Same with the alternative of raising PH, garden lime for the dry amendment option and PH Up for the water additive, normally made out of potassium of some sort, carbonate or hydroxide are the main ones I see. Indoors most people alter the water and call it a day, outdoors is easier to alter the soil its self as rain and such tends to water it. With plants grown in soil. I find the PH can drift upwards without much negative effect on the plants. I aim for 6.5-6.8 baseline and only really try and correct it if the PH goes above 7.5-7.8 their will be pockets in the soil that are higher and lower and it evens everything out. Your plants will also tell you if something is wrong and your plants look healthy, so I don't think there is anything to worry about. I woud keep doing what your doing and if you feel the need to alter PH, using a water additive would be best as not to disturb the roots in flower.
