Description
A great one-part coco nutrient, Hesi Coco is a popular choice and easy-to-use when it comes to working with coco for the first time.
Hesi recently altered their formula for this nutrient and instead of using the same feed for both growth and bloom stages, they now advise using Hesi TNT for grow feed, something we've advised for a long time as it provides the nitrogen growing plants need.
The thing to be aware of is using TNT makes it impossible to get an EC reading as the nitrogen in the TNT is organic and as such does not conduct electricity, making it impossible to use an EC meter. However, as Hesi is quite a forgiving nutrient, using it at 5ml/l dilution is fairly safe.
We recommend starting on a lower concentration initially, so 25ml/10L for clones, then 35ml/10L in the first week and 50ml/10L in the second, depending on the response of your plants.
Once you are using the Hesi Coco feed for flowering plants your EC meter will work normally so using the grow schedule as a guide should present no problems.
As with all Hesi nutrients, using the full range of Hesi additives should improve the health of your plants throughout their lifecycle and if used correctly they should also increase your yield at the end.

How to use
Hesi Coco is a good first feed for coco growers. Hesi now advise Hesi TNT Complex for the growth stage, as it gives growing plants the nitrogen they need, then Hesi Coco for flowering.
During growth, with TNT, an EC meter won't read properly, because TNT's nitrogen is organic and does not conduct electricity. Start gently: we suggest 25 ml per 10 litres for cuttings, 35 ml per 10 litres in the first week and 50 ml per 10 litres in the second, depending on how your plants respond.
Once you are on Hesi Coco for flowering, your EC meter works normally and you can follow Hesi's schedule. The rest of the Hesi range, such as Root Complex, works alongside it.
Questions
Why won't my EC meter read Hesi TNT?
Most of the nitrogen in TNT is organic, and organic nitrogen does not conduct electricity, so the EC reading is low. Feed by dose rather than EC during growth.
Do I use Hesi Coco for growth?
Hesi now advise TNT Complex for growth and Hesi Coco for flowering.
Hard or soft water?
Choose the hard water version if your tap water is hard, and soft for soft water.
