When using a two part base nutrient such as Hydro A&B and Coco A&B, you should equal amount of both parts, added separately.

Therefore if a feed chart says to use 4ml, you should use 4ml of part A and 4ml of part B. If the feed chart says to use 2ml you should use 2ml of part A and 2ml of part B.

In a word, NO! Soil is completely different to coir and other inert media in that it regulates the nutrient content and pH by itself. There’s a tendency to over-complicate things with soil and spend time adjusting pH. But over a single grow/bloom cycle, Plant Magic Soil Supreme when used in conjunction with our feeding schedule can provide a full balance of nutrients to the plant. As long as the soil is not over/under watered and has not become too cold.

The run-off from soil does not represent the true pH at the rootzone. Many growers make the mistake of measuring the run-off which is not an accurate reading for what is happening around the roots.

The general rule of thumb is that anything below an E.C. of 0.4 is considered soft water. The pH can be less accurate in determining hardness as different metals in the water can raise or lower the pH more than others. An easy way to help judge if you don’t have access to an EC meter is to check your kettle for limescale, the more limescale the harder the water! Alternatively, you can take a sample of a few hundred millilitres to your local grow shop and ask them to test it for you.

HOWEVER, the supply of water delivered through your tap can be different to your neighbours tap and can even vary from day to day depending on which water source the water company is getting its supply. We advise all growers to check their water hardness every month to avoid deficiencies.

The amount varies depending on the number of roots and the size of the potting hole. We recommend using approximately 20g when potting up into a 10ltr pot. This should provide the potting hole with granules all around it, allowing maximum contact between the granules and the roots to get them to work.

When potting up from a 10ltr to a 25ltr pot, the potting hole is larger so you will need more granules to coat the inside of it. The key thing to remember is you can’t overdose with granules, using more can only give better results.
