im checking the ph of the water before i use it and yes i shoul buy a soil ph tester but as i said this soil is the same brand as i used before as this didnt happen the other times, but i guess even if it is the same brand it is going to vary. when i have the cash i will get a ph meter.
but if it was the soil would it not effect all of them as well?
root rot??? im not a heavy waterer but perhaps the soil tried out in top inch a lot more than below one time: so many varibles....
