ffishermun,
Could you give us some more info or maybe a pic of your plant?
Couple questions:
1. What is your soil mix?
2. What kind of aeration did you use?
3. What was your source for the castings?
4. What do you mean by "stems twist"
It is highly unlikely that the pH of the tea caused this.
I agree that the pH will balance to around 7 in a properly prepared ACT.
In 5 gal of water with just under 2 cups of compost/ewc.
My tap water is around 8.
I add fish hydrolysate and it goes to around 6.5
Within an hour or so it is sitting at around 7
Foam or the lack thereof does not indicate the tea being ready. You can get foam from the earthworm castings or for sure if you add alfalfa meal (highly recommended)
Testing the pH of your ACT is really not necessary and probably not really even considered by the folks that do this for a living. (Just a guess)
It is important to bubble the water in advance of adding your compost if you are using city water with the certain "additives".
Adding a pinch of organic matter (compost, EWC, etc) during the "pre bubble" will help with the chloramine (sp?)
FYI - I typically pour my tea full strength as a soil drench at around 18-24 hours.
If applied as a foliar spray I usually will dilute just so I can spray my backyard too.
Cheers.
Oh yeah. It would be helpful to the general public for people to review the following links prior to making "guesses" regarding compost teas in general.
