The pH of the runoff continues to drop below 6.0 with each feed, resulting with me trying to bounce it back every other watering. I would like for the pH to be more stable. Any ideas why this might be happening? I am using Advanced Nutrients pH perfect - Grow, Micro, Bloom.

Neptune’s Harvest 2-3-1 ok?
Im growing an autoflower in ffof in 3 gal fabric pot. Undecided as to whether to keep indoors or bring outside. I’m starting week 4 and figure I need to start nutes soon. I’d like to go very simple and organic. Can I just use something like Neptune’s harvest fish and seaweed?

1100 or 1500 PPM Co2
Do I keep this 1,100 PPM - 1,500 PPM level for the rest of flower (of course stop 2 weeks before harvest) and is it worthwhile to bump up to 1,500 PPM?

Thoughts on adding GH FloraBloom 0-5-4
1st time grower here- Good idea to add this nute to my almost 4 week old autoflower top-down? I'm using a wicking tub with ocean forest potting mix, that has a layer of fertilizer more rich in nitrogen. They seem happy, would hate to overdo it. Haven't watered them in 2 weeks.

Looking for nutrient advice: I run RDWC (65L) and DWC (50L), 115L total. Need max pH-stability and clean minerals for high-oxygen hydro. Which pro-line handles heavy feeding best without residue? Documenting all EC/pH data and plant response. Suggestions?

Bad ph water, it bounces like a pogo stick
My city water supply sucks. The ph rises and falls in such a wide range that it is difficult to keep up to what it needs to level out the ph. I have seen 5.8 up to 8.9 just in the last month. Is there a cheaper method than using the standard PH down?

What to do? Where am I at now actually? I’m lost and slightly discouraged
When should I add happy frog fruit and bloom? This is my 3rd grow and im 0-2! I have a overfeeding problem but I’ve learned to be corrective and precise with ph and ppm and be pest preventative as well (heavy handed waterer as well..im trying). It’s day 5 of flower and I’m lost

Compost tea pH
Gazillion recipes on line. But my question is about pH. What should the pH be? Is it advised to try and raise or lower it with G.H. up/ down or try silica or lime. Not finding recipes that cover pH adjustment or concerns. I worry about liquids. I've got a bottle of silca blast.

Should I add nutes? If so, with my Fox Farm soil, how early should I be adding said nutes? Fox Farm seems to say everything i need is already in the soil..
My 5 gal cloth pots are layered with approx 1/3 Cali Super Soil (bottom) and 2/3 Fox Farm Ocean Forest (top). I assume when the roots reach the super soil all nutes will be supplied. But what happens until then? Should i provide nutes until they reach the SS and if so what kind?

Adding Bloom Nutes
I'm thinking about adding either Overdrive or Big Bud to the nutrient list so my question is two fold. I think I have probably 4-5 more weeks of flowering is it worth it to add more nutes now? I would also appreciate anyone's opinion on using these independently vs together.
