Plant Magic - Oldtimer Organic Grow - Organic Base Nutrient for Soil, Veg Stage
Best for: soil growers who want a fully organic base nutrient for the vegetative stage, ideally paired with an organic soil mix.
Our thoughts
This is genuinely one of our favourite soil-grow feeds, and it's not just marketing spin - the organic base means it feeds the soil's microbial life as well as the plant, which tends to show in healthier, more resilient growth over the vegetative stage. Pairs particularly well with Plant Magic's own Soil Supreme, but it'll work fine with most organic soil mixes.
Plant Magic Oldtimer Organic Grow is an organic liquid base nutrient for plants grown in soil during the vegetative stage, with an NPK ratio of roughly 5-3-3. It's built from organically derived plant-based ingredients including seaweed extract, humic acid and fulvic acid, which feed the plant directly while also supporting the beneficial microbial activity that healthy organic soil relies on.
It produces particularly strong results when used alongside Plant Magic's own Soil Supreme mix or any other organic soil-based growing medium, and is designed to provide everything a plant needs nutritionally during vegetative growth as a complete organic feed.
How it compares
Organic base nutrients are judged on how consistently they perform without the precision of a mineral feed, and Oldtimer Organic Grow holds up well in that respect.
- Compared with BioBizz Bio Grow, one of the best-known organic vegetative base nutrients, both feed the plant and soil biology together, with brand and price the main practical differences.
- Compared with Canna Bio Vega, another organic vegetative feed, the two occupy a similar space in the organic soil-growing market.
- Compared with Plant Magic's own mineral Soil Grow, Oldtimer Organic Grow trades some feeding precision for the microbial and flavour benefits organic growers are usually after.
If you're growing organically in soil, this is a genuinely well-regarded option rather than a budget compromise.
Usage guidance
Oldtimer Organic Grow is used throughout the vegetative stage, dosed to match plant size.
Dosing
Add to your feed-water at a rate of roughly 2-5ml per litre, adjusting depending on the size and feeding demand of your plants.
Soil pairing
Works best with an organic soil mix such as Plant Magic's own Soil Supreme, where the microbial activity it supports has the right environment to establish.
Feeding schedule
Use through the vegetative stage, then switch to a dedicated organic bloom nutrient once plants move into flower.
