Drip Feeding Soil - Is it a good idea / nutrient advice?

[Hula]

So, I fancy trying a soil grow with a drip watering irrigation system fed from a tank and looking for nutrient recommendations. I've used PM Oldtimer for soil before, but these need used soon after mixing (I believe most organic nutes are the same). So I'm looking for a soil nutrient that can be premixed and won't go off, or get too slimey in a tank if left for a week or two. I've seen Hesi TNT recommended for autopot type soil grows, would it be a good choice?

Coco would seem a more natural medium for the drip-fed approach, but I'm hoping to leave things unattended for a few weeks at a time without the need to regularly check PH and EC levels and I'm thinking soil may be more forgiving. Or...is coco reasonably forgiving if the PH/EC remains unchecked? Likewise in soil, I want to avoid overfeeding or introducing too much salt.

This won't be a perfectly optimised grow, but something that produces reasonable results is all I'm after, so convince me - soil or coco and which nutes are best for a 25 litre tank to feed a couple of plants?

Been doing soil for 20 years , I would not recomment doing that, it would get mucky and very soggy , Coco would be better , or automated hydro system , but definatly not soil . you would get diseases in no time
