Always used GHE now TA, a very professional brand, I still rock the same bottle since 2022, a couple of mls and it grows whatever you want. The Micro unfortunately it clumped a bit, but nothing that a good shake can fix.
Cheapest CALMAG I could find back in the days. I have a couple bottles since the covid days, it helped me grow very nice tomatoes back then and now some nugs too.
