Our Feed Chart is only a guide to get you started. It is a moderate, safe feed strength but may be too weak for many situations. You should always adjust feed strengths based on your own observations. Factors that may affect feed strength are strains, water frequency, lighting intensity, pot size, and VPD.
There is a long-standing misconception in cultivation to start light and feed stronger the older plants get. However, as the plant matures and dries out quicker, the feed strength should actually be decreased to avoid burning. This is what we call the Crop Charging Grow Method.
In a small, fixed container a young plant will take longer to dry because the roots are underdeveloped. EC needs to be higher so the plant has enough food to grow. As the roots develop, dry down becomes quicker and EC can be reduced. Because irrigation frequency increases, the media fertility stays in the optimum range.
Crop Charging also promotes the internal storage of nutrients, carbohydrates and proteins in vital syncs within the plant tissue. While EC is high and food is available, the plants build up these storage sites for later use without compromising day-to-day growth. Later in the plants’ life cycle, it will utilize this stored energy for flower production.
Root zone pH can affect nutrient uptake rates. Using the right pH for your nutrient solution is a combination of understanding your media, climatic pressures, irrigation practices, and feed conductivity among other variables.
Typical pH ranges are between 5.6 - 6.5.
Extra care must be taken with amended soil medium to make sure your fertilizer feed is applied at rates that compliment the unknown NPK value in the soil. We recommend using certified facilities for soil testing to determine the best amendments, compatibility, and application rates.
Our feed charts work very well, but are only a guide. If you have existing cultivar/system specific feed charts, you can match your existing weekly EC targets while keeping the proportions in our feed charts. Another option is to start at half strength and gradually increase, while carefully observing the plants.
Yes, 0.5 ml per gallon of RO water. A surfactant is already built into the Si, no need add other products.
Yes, stock concentrate clone application is 9 mL of Part A, 9 mL of Part B and pH between 5.6-5.8.
Direct to reservoir clone application is 2.0 grams Part A and 1.4 grams Part B and pH between 5.6-5.8.
Front Row Si can be used at 1/2 mL per gallon.
Front-Row Ag uses the highest purity and grade agricultural inputs. Front-Row Ag does NOT use pre-blended micros, solely repack other manufacturers raw ingredients, and we DO individually blend each of micronutrients, chelates, and other added technology with each custom blend. Front-Row technology includes proprietary complexing agents, mixing methodology, surfactant, and sterics.
You will not need additional Cal-Mag when using Front Row Ag, we specifically designed the formulation over 6 years on Coco Coir media – then moved to stone and rock-wool. This pertains to all situations. If deficiencies are observed, we recommend increasing all parts to keep all micronutrients balanced.
Front Row Si uses an advanced stabilization technique that does not require PEG (Polyethlene Glycol) like some other brands. It is has 10% MSA and a higher level of plant available Silica.
It is also more cost effective (less expensive). Front Row Si also has a built in surfactant and can be used as a foliar feed at 0.5ML/gallon.
No. You will not need an additional bloom booster when using Front Row Ag Bloom. This contains all the needed micronutrients, plus ideal quantities of P-K, to allow you to maximize density, quantity, and quality.
Yes, sourcing the highest quality inputs ensures the lowest heavy metal. We have had many commercial facilities in many states pass heavy metals testing in states such as California, Massachusetts, Colorado, and many more.
