Hi, I am new here and new to trying to grow. I currently have 2 plants started from medical in which a friend gave me two seeds and they are female. My husband built a grow box and it has been working well. Using a LED Grow light and is about 30" away from plants. The pots have good drain holes and are sitting on a base that allows them to drain when watered. I didn't realize I should have pruned the plants and they are beginning to bud so guess that is now out of the question. One of the plants looks a lot healthier then the other. One of them the leaves are brown on the ends and I just noticed that the leaves on one of the umbrella's (it is what it looks like to me) is turning yellow. I also noticed that the soil is really strong smelling of cannibus….it that normal? I do have gnats but I also have the yellow sticky papers up catching them. The soil I am using is Fox Farm Ocean Forest soil. I have not added anything else to the soil. I water when almost dried out. Please give advise !
