City water or well water?
I use well water all the time and don't touch it - its fine. As far as city water I'm sure that if u just let it sit out for 24 hours you'll be fine.
Your mix, depending on how much of each item was used per CF of soil, seems like a hot soil, which is fine, but I have found with hot soils that they need microbes to cycle that many nutrients and time - sometimes 30 days might just not be quite enough, depending on how hot the batch is - do you get what I mean?
The plant(s) honestly look fine. Its hard to tell with pics sometimes due to lighting, but unless you see the little yellowing/funky lower leaves spreading north, I personally wouldn't sweat it.
Again - great work!
Make up yourself a simple ewc w/ a teaspoon of molasses aact and root drench and foliar feed if you're worried at all. Let the microbes work their magic - or, simply topdress w/ some good quality ewc or vermicompost or an inch or so of good compost.
Again - microbes.
Its city water and yes its always left out to evaporate, but ive been hearing they are putting chloramine in water supplys now, which doesnt evaporate like the normal chlorine would, but i cant for the life of me find out if NY uses chloramine.
I get what u mean, i dont think the mix is THAT hot though because its been growing in this mix for a whole month now, so im pretty sure everything has been broken down for some time.
I did give it some compost and ewc top dressing last week, and an aloe w fish n seaweed foliar two days ago, so thats covered.
Maybe i am just worrying too much, it is just the small old growth that gets no light thats being affected, but better safe than sorry.
