PH Levels - Watering vs RunoffAfter my first transplant, I saturated the grow medium and did a PH test on the runoff. I'm watering with un-PH'd aerated tap water which is naturally at 6.5. The runoff water is coming in at 5.5. Should I alter the PH I'm watering with so the runoff meets my PH target?Week 1

Soil pH not adjusting even after watering pH water.So Far I've been 6.5-7 pH water, & organic ferts BioThrive Grow, Bloom & CalMag. The soil pH doesn't seen to go any below 6.5; even though I've been feeding 5 pH water to make it lower. Why is this happening? What to do? Does organics in the soil auto-adjust the pH all by itself2y ago

Help me avoid over/underwatering my girls..Almost done with 1st week, watering my girls 50-60ml each, once a day in 2L pots.
It's 28C (80F), humidity around 65.
I check the soil (1inch deep) but still feels a little wet even after one day.(despite little water and 80F)
Should I still water them as they are still seedling?Week 1
