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.

what are your recipes of super soil, what kind of KNF methods do you use ?
Does anybody make their own super soil? What are your homemade recipe? I think the future of cannabis growing is all about micro organisms and the soil health and I think korean natural farming, bokashi tea, and super soil are natural methods of getting a good quality of bud imho

High Runoff EC. Possible toxicity?
My runoff EC keeps climbing, I've watered just plain water in between feedings to try combating it but it climbs back up. Am I doing that right? Should I be diluting my solution and keeping the ratios the same? Please, any advise is welcomed

Could someone please explain the precise mechanism underlying the phosphorus anomaly? As anticipated, availability decreases with increasing pH, yet it exhibits a sudden surge at pH 8.5. What is the exact (bio)chemical rationale behind this phenomenon? Boron has a similar pattern

Nutes after transplant and spring water
Hello, I have recently transplanted my green friends, is it time for me to start using nutes or should I wait for a bit after the transplant (possibly stunted)? Also I'm using spring water which is 0.0 EC, should I always use calmag to raise it up to 0.6 EC before adding nutes?

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.

Does adding extra PK in an organic grow extend curing time ? Thanks !
My friend that uses Biotabs nutrient as I do achieved a better taste than I did on our AMS Wedding cake seeds. Tastes a bit like mustard whereas his is tasty even though they were all dried just 2 weeks ago. My leaves were always dark green , Maybe adding PK wasn't necessary ?

Does this look like minor leaf burn, too many nutrients or something else?
I believe two of the plants developed minor leaf burn. One has white streaks on the middle and outer portions of several leaves, and the other has a rust, reddish stripe parallel to the center of several leaves. I’ve attached pictures above. Thoughts are greatly appreciated.

Nutrient burn?
I believe I overfertilized this week. I am using a four bucket DWS system with Reservoir bucket. This is the last week of my veg and I might’ve been heavy handed with the fertilizer. At one point my solution was 1844 ppm. I usually run itbetween 8 to 1200 ppm. I delutedd the solution in half. I didn’t have time to change it all because the lights are going out. Do you think this is nutrient burn? Thanks

Run-off Results to high?
My first reading (after pouring 6 quarts of water thru the coco medium) was over 4900 PPM. After another 6 qts it read 1995 and after a third round it read 908 PPM. This is my first time doing a run-off test, should the PPM be lower?
