Sounds like a quality mix to me. :thumbsup:

But is it buffered to a neutral ph? Does it say anywhere if there's limestone or limestone dust added? (the most common ph buffering additives) If it's not buffered, ph will quickly dive.

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