someone had said your soil might be too hot, means your soil might have too many ferts and/or out of range pHI am waiting on a PH UP and DOWN testing/regulating kit to arrive by mail... PH is without doubt a problem (that is in my case directly linked to the sh#@ soil used, I am also waiting for the delivery of a bag of Fox Farms Ocean.. soil) and temperature is also a very big problem for those plants... I need to get PH higher and temperature lower... Hmm air conditioning 24/7 seem the only way to go...
Flat stem = too hot ?
Also I speculate that your soil could be too hot if the stem became flat, I think I read you right. But I can't give you a definite answer.
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... :
