how long till i should have colas on my tnt and master kush plants by eva seeds and dutch passion. they have been flowering for about two weeks maybe two and a half. they have many popcorn buds all around.
The word cola just means a main verticle stem. Allowing a plant to grow naturally will result in one cola. Techniques like topping, FIMing, LST and Scrog aim to increase the number of colas. You are asking when you are going to get buds forming on your colas. The answer is within the next few weeks. It can take almost two weeks for the plant to even realise that you've changed to 12/12, so be patient. Do you have all your nutes and pH good and do the plants look healthy?
