what kind of water are you using ?
do you check your ph
you have the starts of micro and macro def so i would look at ph
but what's in water can throw off ph as well is why i ask

 

[Skunky Smurf]

oops and what kind of mix are you using?
how often do you water?
what are your temps and humidity ?
sorry but ....yeah?
start there

thanks for the reply.. i think it was the ph my soil was a ph 5 ano thats bad cos it will lockout nutrients so i used ph up and i will see how thing go

ph could be from your medium
but what caused it is really the question?
you had a very low ph could water to often?
could be the nutrients your using"
what kind of water ? is it chlorinated?
if your water has chlorimine instead of chlorine the combonation of the chlorine and ammonia used can do this as well?
but atleast you have it stable? for how long?
