hi there i was just wondering if you can use just one formula for growing vegtables instead of two , for e.g.. part a vegetive growth and part b for fruiting is it possible to have one that does both i grow vegtables outside in coco coir and perlite and hand water them i want to set up a drip system and would be much easier with just one formula i make my own nutrient formulas and am useing two at the moment
