Thank you!!!
I have
fox farm as well
Yes I think I have slurry and runoff confused. I've only done the slurry test taking soil from the top, mixing with same amount of water, etc. Not sure what a run off test is. I have an idea but not sure how you take that. Just grab and put into a cup and test as it runs out?
When I flushed last few times I only did a gallon of water. I strarted flushing as well a few weeks ago first because my water started sitting on top and my plant stopped taking up much water
After the flush that problem went away.
I last flushed yesterday with a gallon. I have zero runoff. I'm a newb so didn't know you flush with more. So to ph adjust, my water is normally 7-7.5ph, and to bring that down I have
Herculean Harvest bone meal that brings the ph down. Otherwise I need to purchase some ph down. Never had an issue with ph tho doing mixes. Maybe more so just flushing because I'd need to add that herc harvest to lower it. I also have photosynthesis plus that I use as a tea.
My ppm with tap water is around 350ppm. Reverse osmosis water shows 0. If I mix the 2 together then it's around 140ppms.
