>>20119403I really doubt the price in the stores will be so much cheaper than from ordering online.
They don't sell pots on Home Depot or something?
>>20119404There're kinds and kinds of gardening soil. Some already have fertilizers and some don't. The ones that have fertilizers can have only organic ones or only chemical ones or a have mixture of them.
But the worse part is that most of the time the manufacturers don't specify objectively the quantities of fertilizers the substrate has, making all the issue a fucking guesswork and compromising the final result (yield).
Because that I way prefer to make the substrate myself from raw materials and then fertilize it.
If you'll be following my suggestion don't spray the fertilizer while the plant still a seedling. The vermicompost on the substrate is enough for that beginning phase. Wait for at least three pairs of true leaves to grow out, and do not overdo the spraying. Just a bit here and there wetting all the leaves is enough, don't need to drench the plant.
Use it on ALL phases of the plant, especially on the flowering. In the last week before your planned harvest you don't need to spray again.
