Mazar doesn't get that tall. I have been topping my auto blue mazar which is a little taller than the straight indica mazzar. I top just above the third node. I don't think it makes the plant any shorter. Cutting back on fertilizer will keep them from growing taller than they should. Depending on light I have found best way to deal with too tall plants is to let them grow and if it really gets out of hand to trim (seriously, no joke) about 6 or more depending on how close you are to the light inches off the top buds assuming they are in the very early stage when they are not quite ripe but will give you a buzz when smoked although longer would be better. I was surpised how well the remaining buds heal and after a week begin to look just like the top buds. I have also not found lst to be a solution for height. These are gong to grow the same height whether they are starting from a vertical stem or a horizontal stem. Almost nothing with autos is even discussable with photo growers, they just don't understand what we are talking about. at anyrate, that Mazar is a tough good yeilding easy to grow indica if you like sitting on the couch. Shouldn't get more than 3 ft.
