An e-mail to the company asking about the ph would answer this, if it's not listed on the label.


Yes, I see two of those: Dolomitic Limestone, and Calitic Limestone. Apparently this soil is from Quebec, Canada.

Also -
Transplanted girl in new soils seems to have halted symptoms, she is now a complete shade of green lighter than the other and is looking healthier. The other is darker, new growth is an almost neon green compared to that of the transplanted, and she is doing worse, the nutrient burn is spreading, so tomorrow I'll fix her up like her sister.
Probst Reviewed by Probst on . 2Week old plants, curling, spotting, yellowing Hello everyone, Thank you for taking the time to open my post and read it, I really appreciate it! For those of you who do not wish to read the rest of the post, and simply wish to know the problem - TL;DR: I think Marsha and Cindy have a calcium deficiency caused by pH levels locking out nutrients. Testing pH reads 6.8; I have heard differences as to what the pH level should be, but I believe I am in the correct range. Perhaps I need to begin fertilizers? Background history: Rating: 5
