Marijuana seeds are dicotyledonous. The seedlings will acquire energy through a process that breaks down food material stored in the endosperm of the seed. The role of creating energy is assumed by its cotyledons or baby leaves.
Once your seedlings have used up all their energy, they will require nutrients from an outside source. This is where the grower comes in and gives the plant its first feeding of nutrients. Lets talk about when is the right time to start feeding your cannabis plants and how to give them their first dose of nutrients.
Once your plants have grown sets of true leaves, you can give them their first feeding of nutrients. It usually takes about weeks from planting your germinated seed for your seedling to have used up all the energy left in the seed. Your plant roots are now taking nutrients from the soil and from any added fertilizer.
This is also the time I like to transplant the plants to a larger pot. After the transplant, I will give them their first low dose feeding. This is day one of the vegetative stage. The size of your planter will determine the volume of nutrients you need to give each plant. The runoff will help guarantee that your soil is completely saturated.
Another trick growers do is pre-water their soil 30 minutes before giving them nutrients. This also helps your soil absorb more water. This plant was transplanted, topped, and given its first low dose feeding. This is the same plant 9 days later. It is getting its second feeding. Mixing fertilizer with water and feeding your plants is a simple process with a product like Reefertilizer.
First, you will want to know how much water you will need for your pots. Young seedlings, when the plants begin to grow leaves, and when they begin to grow fruits are crucial times to get them the essential nutrients for maximum yield and health. You might need to use nutrients in the soil before planting the seeds if the soil is particularly lacking of nutrients. Seedlings need diluted nutrients so that they are not harmed by high amounts of nutrients.
For seedlings, use potassium rich fertilizers. Depending on where your plants are will change how often you fertilize them. If they are in a container then once or twice a week should be sufficient. That's because the natural nutrients in soil are more readily available. Outside, the soil is going to have more nutrients than inside. It's recommended to test your soil prior to planting seeds.
That way, you can see the exact amount of nutrients currently in your soil. Then, you can gauge what nutrients you need, how much of each you need, and how often to apply them. The N-P-K ratio is the amount of nitrogen, phosphorous, and potassium in a fertilizer. The fertilizer label indicates the ratio of N-P-K. Fertilizer is a concentrated amount of nutrients but potting mix is soil with nutrients in it, but isn't as concentrated.
It's important to differentiate between potting mix and fertilizer when deciding what to use for your plant. If you need a high dose of nutrients, then you should use fertilizer. No, only use nutrients once or twice a week. Adding nutrients more often creates a buildup of excess nutrients that can harm plants.
Testing your soil or hydroponic solution weekly to make sure you have proper nutrient levels.. If you water your plants directly after using fertilizer, you can run the risk of flushing the nutrients out of the soil. So, wait a day before watering the plants so they can absorb nutrients.
Besides gardening, he's an avid wildflower enthusiast, and loves botanizing, hiking, and backpacking. Quick Navigation About plant nutrients and seedlings. When to add nutrients to seedlings. All returns must be accompanied with the original packaging, all accessories and in new condition.

Or can I get away with using plain water?
These nutrients are used to build the structure of a plant as it grows from its roots to its flowers. Without adequate phosphorus, marijuana plants will show signs of undeveloped roots and might not even flower. Early signs of phosphorus deficiency shows up as a purple hue in the veins of leaves. Potassium has a number of jobs that largely help regulate the systems that keep a plant healthy and growing. It plays a large role in osmoregulation, the passive regulation of water and salt concentrations in the plant.
Potassium accomplishes this by controlling the opening and closing of the stomata—the pores in the leaves—which is how a plant exchanges CO2, H2O, and oxygen.
Potassium also triggers the production of ATP, which works to store energy produced in photosynthesis by creating glucose. This glucose is then used as energy for the plant as it grows. Without sufficient potassium, you will see weak plants starved for energy that appear burnt because they are unable to successfully regulate the exchange of CO2, H2O, and oxygen.
Calcium is responsible for keeping the structure of cell walls in a plant together. New growth will be stunted, leaves will curl, and rusty spots will show up on the plant. No magnesium means no energy can be converted from sunlight. Once magnesium has helped create glucose, it helps metabolize glucose to make it available for the plant to grow. Without sufficient magnesium, you will find yellowing leaves, with discoloration reaching the veins as well.
A general rule of thumb is that a vegetative fertilizer should have high nitrogen, low phosphorus, and moderate potassium: for example, As a plant transitions into flower, taper off the nitrogen and focus on phosphorus and potassium—seek a ratio around , for example. In the final week or so before harvest, be sure to give your plants only water to clear any nutrient buildup in the buds—this is called flushing.
Liquid nutrients are typically used for indoor growing, but can be used outdoors too. Liquid nutrients are used for weed plants in soil, hydroponics, and other grow media, and can be pushed through drip lines, misters, and hoses for easy and efficient delivery. It depends on the complexity of your soil and the health of your plants.
Too many nutrients will damage your plants.
