ADHD2THCanswered grow question 4 years ago By feed, do you mean add nutrients? Every day for anything is almost always a bad thing. If not using a wick system or hydroponics, watering 2-3 times a weeks is more than sufficient(but always depends on the plant and environment. As far as nutrients go, unless its in coco coir or you aren't growing an auto flower, you probably need far less than you think you will and it can be quite easy to over do. Do some googling about the topic, and if all else fails, RQS has a very informative and easy to read blog with plenty of information.
