So I have the soil, lights, seeds, etc... And I'm just wondering how much and how many times a day do I feed the plant water?
You water every 3-4 days or until the soil in the pot dries out almost completely. Google "How to grow marijuana" and read every article on the first page.
Every other watering if it isnt to rich. Fallow the instructions on your neuts, but make sure you dont put to much neut in the water, wait for your soil to DRY out, not quite wilting, but close. If you see any burning, stop and flush. Pot : 101
