Cheap PH down?
smokeyspartacusstarted grow question 5y ago
Is it just me or is GHE/AT PH Down very diluted?
I started with gGrowth Technology which is 81%. TA PH down has nothing stated on the bottle...
What do you use as the cheapest way to get PH down in circulating hydroponics/DWC?

Not sure if it works with hydro/DWC but citric acid is a cheap pH down. It’s water soluble so I’d imagine it be ok. Worked great for my organic grows.

Does low ph runoff need attention?The ph run off of my plants has been consistently low, ranging from 5.5 to 6.0.
Should I be concerned? The soil is Fox Farms Ocean Forest. The plants are OG Kush and Gorilla Zkittlez Autoflower. I’m feeding them straight tap water with a ph of 7.5-8.0.Week 6

Should I switch to well water?I use tap water. For our normal flower/vegetable garden we use well water. I measured the EC/PPM of both.
Tap: 0.5 mS/cm (=320 ppm), we live in an area with soft tapwater according to Water Agency (11°F-13°F max)
Well: 0.32 (=205 ppm) -> how do I interpret this for well water?Feeding. Other

Super low runoff PH, even after corrective measures being taken. Plant otherwise okay, but probably isn't taking all her nutrients.My runoff PH has been hitting mid-5s, even after flushing (w/ & w/o additive). Been trying to raise with higher PH water, used 7.25PH water today and the runoff was still 5.56. She looks healthy other than some discoloration in some leaves, so it isn't killing her but.....????5y ago
