Soil runoff 5.5 due to daily watering with ph down?

Rookie mistake. I was trying to get my water to around 6.3 for every watering which required like half a tsp of ph down per gallon thanks to my 350 ppm tap water. live and learn.

Got my RO system yesterday and will use dr earth dry amendments instead of fox farm bottle nutes for this round (and no ph down either).

Ah we all make them mate, like you said, live and learn! Soil is very forgiving when it comes to pH.
Good work man, keep that pH down aside and just go from there, you'll be sweet!

I might point out that your under feeding for the first thing!

The plants SHOW it!

Second of all: The Ph of run off is just that - THE Ph OF THE RUN OFF - NOT THE SOIL'S

Installing an RO - First step to real control of your feeding!

There SHOULD be enough forms of Ca in your soil to take care of it.
You do not need to "remineralize" RO with soil use!
NOW, if you do ANY form of hydro - including soilless. You MUST use a Ca/Mg product - use one that is Calcium Carbonate based for better Ph control.

Be careful NOT to drop the N and up the P in Bloom to much! The change is different than most nutrient makers claim and chart!

Good luck

Thanks for the advice. My RO is installed and ready to go. :) This next grow will be my 4th. So far I've only stuck to foxfarm products and will finish this grow with them. Trying my luck with organic dr. Earth dry amendments next time. Hydro is something I may try down the line but probably not anytime soon. This is how they look now. Day 45 of flower.
Buds seem to develop nicely, but my challenge for next time is to keep leaves healthy throughout flowering.
