What are your temps during lights on and lights off?

You say your Ph is ok, what is it at?

HI,hippie mate,the ph run off is 7.0 i cant get it lower than that it was 7.6 at one point, temps are daytime 20º to 24º and humidity around 45%but some times goes up to 60% when i water.At night the temp goes down to 18-19 centigrade.

Your temps are ok.

Your PH is too high, can you get hold of some PH down?

If not (some people frown on this but I use it all the time) you can use distilled white vinegar.

You need to get the PH lower.

With you PH at the level it is at, your locking out Manganese and Iron.

Seems to me like you might have a magnesium def check in the sick thread

sounds like you are over feeding also.i assume you are soil growing.i would lower the ph some.when i was soil growing,i fed my plants once a week and watered every other day,lightly.using 2 1/2 cups of water in a 5 gal bucket

OK,but my ph is the soil runoff,when i am feeding the ph is 6.4,and i have a ph downer from Hesi because we have a high lime problem in this area.But it is probably what you sad about the mag i´ll look into it.

Your run off is what the roots are living in, you need to lower the PH to compensate for this.
