Looks like
A) Long term overfeeding
B) A Ca issue, possibly caused by longterm overfeeding.
I will go visit the Dr @ the practice and see if she reccommends SensiZyme... I've used hygrozyme and it isn't half as good as voodoo. Part way through this week, after covering the top trays slightly, I will enquire further about the addatives u mentioned. But as you say, in around 3 weeks time the ladies are due to end.

I should be feeding with overdrive for 2 weeks atm, but I'm paused on pH balanced water for quite a while. All was well untill:

1. I forgot to turn the rez pump on and it remained off for 48hours
2. The EC hit 2.2 one day, I think it was because I missed a visit

Before the above two instances occured, all seemed pretty good.

Many thanks rhizome for dropping a comment!!! :thumbsup:
