How much dolomite lime per litre/gallon of soil to raise PH by 1 point? Thanks!

kushinatorstarted grow question 5y ago

Hi there! I overfed my plants a bit, which I think led to a sudden drop in soil PH as runoff is at 5.5 to 5.7. I will give it more water PHed to 6.6 to flush it, but also wanted to sprinkle some dolomite lime over the soil to raise PH. How much should I add to raise it by 1?

Hi mate, testing runoff while using soil is a little OTT and unneeded. Soil is a great buffer and as long as you art giving her 6-6.5 you should be fine. If you are seeing issues with your plant due to PH you may have to check your equipment. I hope this helps, good luck and happy growing

Hydro - 3 strains. What consequences after slight veg overfeeding ? Do they look dark ?I've had technical issues on veg that resulted in a slight overfeeding and now they don't want to feed much (tap water 0.4 + 0.3 nutes), 5 days after 12/12. I'm not sure they will accept very much more, even when I'll introduce flo nutes. Will yield be weak ? And quality ? Thx

PH Tanking in Late Flower 6 days ago, 350ppm constant but PH starting dropping hard. Did nutrient change and things stabilized for a bit at 250ppm. Yesterday, same thing occurring with PPM/PH. Roots are fine, PPM now at 200. Is she being underfed now at this stage of flower? Lower PPM more? Start flush?
