So I have a quick question. One time I topped my plant and of course it grew into 2 shoots. But for some reason one of those shoots died after growing for awhile and never came back (might have been accidentally snipped).....Well now on a different plant of mine one of the tops (I don't know if it's the main grow shoot or not it's just a top) suffered some heat burn bc it grew up onto the top of the greenhouse which was hot. My question is how will I know if the shoot will resume as a top? How come I topped a plant once and two shoots came but when one of those shoots was cut again it just died? Is there only a certain time or place you can cut a shoot to make two? Thanks if anyone can clear this up. Ive been growing for years and don't really know for sure.
