Mango Haze help please with pics

if you prop your plants branches up either tying them up to garden stakes or with strings to something above them,,,you will encourage your plant to really pump out those buds...you will give her the confidence that her branches are supported and she'll go for it..... I have a couple of branches up top that I haven't been able to tie and they are half the size of the ones I've tied up

by the way , how tall are your plants, my plants are three footers . sunlight here is limited at this time of year , but starting next year i will definitely support the branches and see what happens, i cant believe it is so easy to trick a plant .

I dont really grow with height. All my plants are tied down from the start. they got to about 15 inches?
