Why not a side-by-side? Replace the existing mulch on one plant with say, compost, another with straw, etc.So my soil PH. It's low. To be honest, once flower starts I rarely do anything other than some LST and the odd brix check, so it is entirely possible that every grow lowers PH at this point, but I haven't seen it. If this is the 1st time, its pretty much gotta be the mulch.
So heres my dilemma....
I purposely don't use mulch until flip so the roots don't get up into the top 1.5" or so of the pot. All the EWC and topdressing from veg is there. Some of it leaches down, but a lot of it is still there. It's my stretch battery.
So if I remove the mulch I will injure new feeder roots for sure, right at stretch. If I leave it alone, maybe it lowered my PH or maybe the plant/myco system did because thats what the plant dictated.
I am leaning towards letting it be and watching.
The plants aren't perfect, but they are generally healthy and brix is slowly creeping back up with the added light.
They are drinking well and increasing their water intake every day, and every time I turn up the light they say thanks. They just aren't praying yet and they should be.
Drinking is my main concern. If its good the plants are usually good.
So do I strip the mulch or let them be?
The mulch is composted Douglas Fir bark and wild salmon guts. So nutritionally speaking, its Da Bomb. Outdoors it works wonders. This is my 1st time using it in a pot.
What say you all?
My stash is very large so I don't need the weed, and if it goes south I do need the worm food so thats not a factor, should we watch and do bi-weekly soil PH's, or strip it?
I know you have this paranoid thing about keeping outdoors outdoors, but @StoneOtter uses bark chunks from his yard that he sterilizes in the oven if that helps you get over the creepy crawly problem. You'll kill off a lot of the benefits of the compost if you bake it, but it sounds like you've got the perfect setup for an experiment especially since all you really want is worm food.
Plus, with your high brix levels, plant pests shouldn't be much of an issue.
