So I have found bugs on my girls. Very small hard to see but with the jewelers loop my girls are infected. I have Captain Jack’s bug be gone arriving soon. What else can I do to manage the insects. Indoor grow in a tent no outside influence. I have three plants about month away from Harvest my leaves are turning yellow.
It’s end of life normal fade. Your plants actually have excess nitrogen.
You’re on the right track.
Let the soil go dry until then, especially if their soil dwelling or surface soil pest. Do you have a pic 
PURE CROP ! is also available for removal of some bugs.
