I cut my stretchy strains back. I'll keep cutting them back till I get the desired height in my plant canopy. I'll do this up till 3 wks in flower.

Tall or stretched plants are often caused by light from the 2700k(red) wave band,
if you have lights with more than 2700k, warm white bulbs,
more than cool white, blue or 6500k then these plants will be 'out of balance',
or have stretched internodes ..
ensure you have an even balance of warm red and cool white for correct
and balanced plants,
also in your case under watering too can be a cause ​

A. It's a sativa-dominant strain and they tend to tall and scrawny.
B. Almost every time we see a plant like that we have to look at the lights. Most stretching is a result of the plant trying to get closer to the bulb.

I would jack them as close to the light as possible next time. The big plant is too late to modify without spending extra time.

Good luck, BigSteve.
