Grower Tip
- For best results, add Rootzone at 1mL/L to your Complete Focus mix to keep roots healthy from seedling to harvest.
- Mixed more than you need? The solution keeps for one to two weeks. Give it a good stir before you feed.
Features
Single Part Technology puts all 12 essential minerals, including calcium, in one liquid concentrate, with no A and B parts to balance.
Suitable for all plants, from herbs and leafy greens to vegetables, fruit and flowers, through vegetative growth, flowering and maturity.
Buffered to keep all 12 minerals available to the plant, with no pH adjusting needed in most tap water.
Made from high-grade raw materials with chelated trace elements, so the nutrients are highly bioavailable and easily absorbed.
Guaranteed free of chlorides, urea and sodium.
Works in hydroponics, semi-hydro, soil and potting mix, with a simple dilution rate for each.
Completely odourless, so it suits indoor plants and grow tents.
This 20L makes up to 4,000L of working solution at 5mL per litre.
-
1
Dilute for hydro
For hydroponics and semi-hydro, mix 5–10mL per litre of water.
-
2
Dilute for soil
For soil and potting mix, mix 3–7mL per litre of water.
-
3
Match the strength to the plant
Use the lower rates for delicate plants such as herbs, foliage and leafy greens, and the higher rates for heavy feeders such as vegetables, fruit and flowers.
-
4
Feed at every watering
Use it at each watering for best results, or at least once a week during active growth. Most plants need little or no feeding over winter.
-
5
Build strength gradually
Increase the rate as plants grow towards maturity, but never exceed 10mL per litre. Stronger mixes can burn roots and leaves.
-
6
Flush once a month
Water through with plain water once a month to clear any build-up of mineral salts.
How long will the 20L last?
At 5mL/L this 20L size makes up to 4,000L of feed. As a guide, a 200L reservoir changed weekly uses 1L, so the 20L covers about 20 changes. Feeding at the full 10mL/L halves that. Complete Focus also comes in 250mL, 1L and 5L, all with the same formula, so it's easy to move up or down a size.
What's the difference between Complete Focus and the other Focus nutrients?
Complete Focus is the all-rounder, balanced to suit all plants, so one nutrient covers a mixed collection or a whole garden. The other Focus nutrients are each tuned to one plant type, such as Foliage Focus for lush foliage plants or Native Focus, a low-phosphorus formula for sensitive natives. If you mostly grow one type of plant, choose its Focus. Otherwise, Complete Focus is the simple choice.
Do I need to adjust the pH?
Usually not. Complete Focus is pH buffered, so with most tap water there's no pH adjusting to do. Tap water is the best choice for mixing, because its natural buffering keeps pH steadier than distilled or reverse-osmosis water. If you run a hydroponic system and monitor pH, the ideal range for most plants is 5.5 to 6.5.
Can I use it on seedlings or as a foliar spray?
Yes to both. For seedlings, keep the mix weak, no stronger than 5mL/L for the first few weeks, then build up as the plant establishes and starts growing strongly. As a foliar spray, use no more than 5mL/L and avoid spraying in direct sunlight or the heat of the day. Leaves take up nutrients as well as roots, so it's a quick way to give a plant a boost.
My potting mix already has slow-release fertiliser in it. Can I still use Complete Focus?
Yes, but halve the dilution rate so you don't overfeed. With a pre-fertilised mix you can't be sure which minerals are in it, or how much. For best results, grow in pure coco fibre. It holds water well and has no added fertiliser, so your plants get exactly what you feed them, which makes it a perfect partner for Complete Focus.
What are the 12 essential minerals, and why do they matter?
Plants need nitrogen, phosphorus, potassium, calcium, magnesium and sulfur in larger amounts, and iron, manganese, zinc, copper, boron and molybdenum in trace amounts. A shortfall in any one holds growth back, no matter how much of the others is available. A basic NPK fertiliser supplies only three. Complete Focus supplies all 12 in a form roots can take up straight away.

What it's formulated for
A complete, balanced feed means a healthier plant. Complete Focus is formulated for:
- Faster growth and development
- Stronger root development
- Profuse vegetative growth
- Bigger, brighter flowers and blooms
- Greater resistance to disease and tolerance of environmental stress
How to use
- Hydroponics and semi-hydro: 5–10mL per litre of water
- Soil and potting mix: 3–7mL per litre of water
- Delicate plants such as herbs, foliage and leafy greens: use the lower rates
- Heavy feeders such as vegetables, fruit and flowers: use the higher rates
Use at each watering for best results, and gradually increase the strength as plants grow towards maturity. Flush once a month with plain water to remove any build-up of mineral salts. Store in a cool, dark place.

I have never grown more chilli’s on one plant in a pot before using chilli focus. I tried Poblano chilli’s for our green chilli sauce and got a bumper crop, amazing product. Photo of my Habenaros in the ground , already harvested my Poblanos
Excellent product 👍
Love this products. Highly recommend.
After using for a month my Kaffia Lime leaves are growing Wild and Health. Plenty for laksa dishes and other asian curries dishes.
And more than enough for the caterpillar to eat. The butterflies love to lay their eggs on the kaffia lime leaves. This year I am looking forward to see the caterpillars turn cocoon then to new butterflies.
Thanks to the Complete focus. It is awesome products.
Super happy with this product will highly recommend it dose everything it says and more 👌
Absolutely love this product, I saw results in the first week I was so excited, being an avid gardener you will do anything to make your garden happy and with complete focus my garden is singing and so am I.
Usually being a GT Foliage Focus girl I decided to try something different with my outdoor plants. This stuff is awesome, it had plants that I didn't even know flowered flowering!
These products are easy to use with clear instructions. I purchased complete focus and cloned purple.
I have so many plants that it has become an indoor obsession! Have to use top quality products for all of my plants. Don’t hesitate to buy. I used in all of my plants and I have seen results in 2 weeks, greener, stronger and healthier l.
Thanks guys ✌🏻😊
Plants love the GT Complete Focus , very impressed with Grow Kings on the availability of buying in bulk and quick postage times. I will be back
I read the reviews of this as I already use Foliage focus and Flower focus. This seems to take the place of both, and I can already see the difference in my plants after only 2 weeks.
Been using it in my garden over this very hot summer and my plants look luscious and healthy.
Really good nutrient, very basic. Don’t need to worry too much about overfeeding, Works great for younger plants. Noticed such a difference I bought one for my mother as a gift with foliage plus aswell
This wonderful product is used in my two Urbipods hydroponically, which sit on a kitchen bench top. I have tried others from time to time with poor results of growth. Grow Kings have certainly got the recipe correct for this awesome product! I have also used Native and Rose with amazing results. Thumbs up 👍 Karen C
I have been using Complete Focus on the indoor plants for about 5/6 months and the results a joy to watch.
I like having Begonias inside but they all seemed to rot, leaves drop off weak growth and on and on.
I kept a photo record of one Begonia to show what did happen. From a stub in the pot that eventually produced a 5mm leaf so I started feeding it with Complete Focus and like the bean stalk it eventually produced a few flowers.
Photo 1 taken 28/10/24; Photo 2 on 14/11/24; Photo 3 on 5/12/24 and Photo 4 on 8/01/25 and it is still going.
The main improvement has been with an increase stem size (diameter) and improved leaf colour plus very good flowers. The Complete Focus has added much better vitality to the plant.
I do hope you receive the photos from my mobile phone. I'm not much of a Lord Lucan so fingers crossed.
My sole orchid that I thought had GTG has now produced two large new leaves
I have been using this product for
my urbipods plant growth for over a year now. I have tried two other products of which never achieved a result. I thoroughly recommend this product. Karen C
Honestly ive used so many different brands and products for my infoor plants but it all stops here! This stuff is amazing. Litrally had healthy new growth within a week after applying, even on my slower growing plants! Very impressed. Everything looks happy and healthy. This was the missing link i was looking for. Cant wait to try some other products from the same range.
Great products!
