About to give up

Your recipe is listed differently from mine. I use 5ml of Miracle Grow and 1ml of Kent's Essential Elements. said:
Have you tested the nitrate and phosphate content of the phyto you are dosing marc?

How long do you let yours mature?
 
No. It is rather difficult to test those as the water is pure green before adding any chemicals.

It can take 14 to 21 days to mature, but what I have found is it can bubble away for weeks on end (as long as 2 months or more) and not crash.
 
How do you know if it crashed? Mine would settle to the bottom and clear green on top (probably green b/c of the miracle grow) and I would have to shake the bottle everyday. After shaking, it would be dark green again.
 
I started at 10 drops (1ml) of miracle grow. As I increased it, my culture would get darker than the last time. So, I'm up to 1.8ml now and will probably stop at 2ml
