I have been using the same 1 liter bottle for over a year and never miss a beat. Great product.

The Dutch Formula nutrients prevent the plant from deficiency of materials necessary for flowering. I do not need the Dutch Formula Grow because I have to avoid nitrogen lockout.

I have been using this product for a long time and it has never let me down. 7 drops in a liter of water for pH 6.5 (4 with fertilizers) and 5 in flowering (always with fertilizer) for pH 6.2. The solution left standing remains stable up to 24. Adjusting a water left standing still does not compromise the ppm value. Recommended

It shall be impossible to say these Dutch Formula nutrients have any effect on her growth. My usage of the nutrients must be improper in many ways, for she would suffer from excess of nitrogen. Probably not for use in growing on compost beds, yet it may not determine if the nutrients have a worsening property in nature. I would like to try them with much more caution next time.
