Tips for growing huh? Horse shit has to be high on the list of what make my plants flourish, the right amount of water, light and food. All that being said to me once the basics of growing plants, any type of plants and a understanding of biology then it comes down to reading your leaves. Root problem? it will show in your leaves early, hungry same deal, burns or def, it's all in the leaves.
Over or underwatering is a big problem for newer growers, a little tip. This is a pain in the ass but here is what I have done to solve whether to water or not to water. When I put my soil in my container, say a 5 gallon bucket with the soil pretty dry then I water the empty bucket. You have to measure the water, My soil will hold just a bit over 1 gallon of water per 5 gallons of soil. So then when I water if it doesn't hold at least 3 liters or quarts then I am watering too soon. Once you do this a few times you will start to know how many days between waterings depending on the weather conditions if outside and inside will be the same most everytime. Remember the days change as the plant becomes bigger but after a cycle of two there won't be much guess work left.
After that it comes down to patience.
