Fertilizing with the 5:1:1 soil mix
Just a newbie question that has been bothering me.
I've made the mix as recommended and added slow release fertiliser. Correct if I'm wrong but is it correct that I should be watering with a soluble all purpose fertilzer regularly? I have chosen one called nitrosol. It has the following breakdown:
10.5% Total Nitrogen
2.30% Total Phosphorus
6.80% Total Potassium
1.68% Total Calcium
Plus trace elements and minerals - 24 Vital ingredients
Given these elements, which includes magnesium, would this be sufficient or would I still have to add lime or gypsum or something extra?
