Just got my sample yesterday. So far I like how easy it disolves.
I'm in promix. Are either of you? I'm wondering if I should be feeding every watering or every other.
I guess I can play it by ear and adjust as needed.
Just hoping for insight.
I got a feeling I'll be ordering a bag as soon as this sample runs out.
I use Pro-Mix HP but not exclusively. I've combined a 50/50 mix using Pro-Mix along with regular black earth. A little amendment is an additional 1 cup of spent coffee grounds and crushed egg shells that I let cook for about 8 weeks. Mix it up real good and dump into a 5 gallon bucket.
The mycorrhizae in the Pro Mix is a beneficial soil bacteria that work in conjunction with the plant roots systems. The plants excrete sugars that the bacteria love and the bacteria, in return, help gobble nutes to give to the plants.
You can feed every time but at lower recommended dosages. I have been feeding every watering at slightly less than 1/2 recommended dosage - 1 tsp/gallon of FF Grow Big combined with .5 tsp/gallon of Botanicare's Cal-Mag. Those are Imperial gallons which are 4.5 liters and are slightly bigger than the U.S. gallons. Watering/feeding is every three days.
They have been vegging for 42 days and no signs of leaf damage. It's the plan to use 1/2 dosage for bloom nutes as well - 1 tsp Tiger Bloom, .5 tsp Cal-Mag and 1/2 tbsp black strap molasses per imperial gallon.
