Look bro, I really appreciate your help (you did help in your first reply in this thread) but I would appreciate you answer the question I asked and not one I didn't ... I have a PH meter (electronic) and I carefully checked the soil and it shows 5 to 5.5 in PH... My question is what would be the signs of a too acid soil ? Could they been similar to what happened to my little rock star ? ... If you really want to know what kind of soil is used, i uploaded the picture just for you "mygirls" (...) ... here but I have to say that personally, looking at the bag, hmmm I have no clue ! Maybe your thai is better than mine... go ahead bro... :
