While I agree with my comrades above, generally speaking, slavish attention to ph levels is not necessary provided you are generally within range. So called nutrient lock outs are more likely misdiagnosis's of issues to do with over watering, feeding and lighting issues. Pay attention to these first.

Hi Ashton ! Ph is one of the most important parameter in any plant growth ! Ph imbalance can lead to nutrients lockout > then it will cause nutrients deficiencies. Nutrients are mostly available (in soil ) in a PH range between 6.0 and 6.5 in the late growth and the flowering stage so a Ph too low or too high can lead to a nutrients salt build ups because at some PH range she is unable to use the nutrients you'r giving to her so it can result a Ph burnt / nutrient burnt. The main differences between 2 strains will be their ph "sweet spot" or their abilities to resist to a ph fluctuation or even a higher/lower range than usual. I won't talk about Hydro ratio cuz you'r in soil so I hope my answer makes you see clearer !!! Happy growing 😘

@ashton_kusher Hi and welcome on GrowDiaries! Well, pH is regulating the way cannabis handle nutrients intakes. Having a wrong pH in your waterings will result in nutrients deficiencies, and/or nutrients lockout. You should never stick to a fixed pH but rather apply a pH range, by moving your pH a bit in each watering or each week. Considering you're growing in soil, you should apply a pH range between 6.0 and 7.0 but I've experienced better results sticking to a 6.0-6.5 pH range, especially during flowering stage. If you're planning to feed with foliar spray, then the pH should be above 7.0. Remember you need to calibrate your pH-pen when you buy it, and 1 to 3 times a month. Hope this helps, keep us up-to-date and happy growing! 👊
