I think you need to loosen soil in container more for it to grow and not yellow. I have a question. How many plants can I grow with one big bag of potting soil or garden soil at Walmart? I am talking about one tomato, one watermelon, one cucumber plant.
Above all, do not use 100% potting soil but a mixture of several soils, for example, for a tomato plant, which is a plant that requires a lot of nutrients, it will need a pot of approximately 50 liters, so plan at least minus 45 liters of soil in total.
The best mixture in my opinion is a mixture of 25% forest soil (first 5 inches at the surface of the forest cover of the soil under the leaves) + 30% potting soil + 25% garden soil (to decompact well if clayey ) + a little sand (5%) + a little well-decomposed manure (5%) + a little compost (10%) and finally a layer of dead leaves on the surface of the pot (4-5 inches).
If you don't have any of that, a mixture of 50% garden soil + 50% potting soil may be suitable, the reason is that garden soil allows the soil to be decompacted, bringing in bacteria and worms in particular : it is in fact a way of fertilizing soil that is quite young with old soil.
So ultimately the simplest way is 25 liters of potting soil + 25 liters of garden soil in a 50 liters pot, for a single tomato, you can choose a vigorous, grafted hybrid variety, plants already a little large in pots in a garden center, they are hybrid graft on wild rootstock which gives a lot of fruit and which can also getting big, it's not a problem with a 50-70 liters pot, you can also choose a 75 or 100 liter pot, in this case you will obviously increase the doses of soil.
For 1 watermelon plant, you need more, because they are also plants that requires a lot of nutrients, in fact you need a bigger pot in my opinion they can get really big , let's say 90 liters pot, but 100-120 liters is better.
For 1 cucumber plant, same or more than tomato, 70-80 liters, because this is also a plant that requires a lot of nutrients , and when it's a bigger pot, it's more nutrients.
Finally, you can add a natural fertilizer diluted in the watering can:
- based on natural wood ash (ash from barbecue charcoal for example, be careful not to take just any ash, it must be ash from natural wood and no other element),
- coffee grounds are also not bad but only once composted so it will be effective the following year, 1 year later (once decomposed),
- you can also use nettle manure (just do macerated nettle plants in water for a certain time (there is the recipe on some sites it is very simple),
- nettle manure can be used, only if necessary, as a spray on the leaves to repel pests. Flowers and aromatic plants around plants can also be helpful in repelling certain insect pests.
