When To Marijuana Fertilize Seedlings

The first fertilizer or feed of a marijuana seeds life is one of the most important. Remember the marijuana seedling is very tender. Keep this in mind when prepping your first marijuana fertilizer formula. Over marijuana feeding a seedling will kill it.

Be very careful.
Under marijuana fertilizer is better and gradually work your way to full strength formula.

Preparing soil with marijuana fertilizer before planting your cannabis seeds is a great idea. Many marijuana growers do this. Preparing the soil for planting is critical to your marijuana seeds success, but some growers do opt to skip this step. Preferring instead to feed early in the marijuana plant growth cycle.

Mixes composed of perlite, vermiculite, and rockwool and other inert media should be treated with a mild application, 300-400ppm, of fertilizer prior to marijuana seed introduction.

By preparing soil before planting the first feeding won't need to happen for sometime.

Feed young marijuana seedlings in soil a 1/4 to 1/2 strength solution of marijuana fertilizer after two to three weeks or after the first set of true leaves appear but only if the soil is not super hot in terms of nutrients.

Generally speaking the fourth week of the marijuana seeds vegetative cycle is a good time to feed.

Though examine your plants in the third week for signs of deficiencies and feed accordingly. Also plants should be several internodes high by this point.

Adding marijuana fertilizer Hormex, Superthrive or some other auxin/vitamin based supplement will accelerate early plant development. It is not beneficial to apply additional marijuana fertilizer to seedlings in rockwool or other inert media until the first set of true leaves appear, at which point a 1/4 to 1/2 strength application is made.

New and experienced cannabis growers mess up their marijuana seeds growth by not timing their marijuana feeding scheduling properly. Developing both a marijuana fertilizer formula and a feeding schedule is important to successfully grow marijuana.

Paying attention to seedlings will allow a grower to time their application of marijuana fertilizer just right.

Not only are chemical marijuana fertilizer pose a significant risk to seedlings, but also organic fertilizers too. Organic marijuana fertilizers do pose a risk. Too much organic marijuana food will burn a seedling just like chemical fertilizers.

One of the best advices to consider is less marijuana fertilizer is better. As you can always add more, but taking away is impossible. Once a marijuana plant is overfed you'll have problems.

But a slightly under marijuana fertilized plant will be just fine. Just remember less marijuana fertilizer is best.

    When to fertilze marijuan seedlings?

  • Marijuana seedlings typically do not require fertilizer immediately after germination. They rely on the nutrients stored in the seed for their initial growth. However, once the seedlings develop their second set of leaves, it is generally safe to begin fertilizing them. It is important not to over-fertilize, as this can damage the young plants. It is advisable to start with a diluted fertilizer solution and gradually increase the strength as the seedlings mature. Follow the instructions for the specific fertilizer being used and monitor the plants' response to ensure they are not being overwhelmed with nutrients. It is also recommended to use a balanced fertilizer with a nutrient ratio of 10-10-10 or similar for young seedlings.

        • Marijuana plants should be fertilized roughly every two weeks during their vegetative growth stage and once or twice during the flowering stage. The amount of fertilizer you use should be determined by the type of fertilizer, your plant’s growth stage and the size of the plant. It’s ideal to follow the instructions on the fertilizer label for the best results.
