This is an aphid, you can tell by it’s long antenna and long rear legs , thrips have shorter antenna and smaller rear legs , @ProctorPot…
There are two home remedies that you can use as organic sprays to take care of your aphid problem. The first spray, tomato leaf spray, works especially well if you also are caring for tomato plants.
To do this, you simply combine two cups of water with two cups of chopped tomato leaves and let it steep for one entire night. You can then remove the leaves by straining the liquid, and pour the remaining liquid into a clean spray bottle, then add two more cups of regular water. You can then use this spray on the leaves of your marijuana plants – focus especially on the bottom side of leaves, where aphids like to live.
Another option for a similar mixture is finely chopping an onion and two garlic cloves, then blend them with two cups of water. Strain the pulp out and spray the mixture on your plants.
You can try an organic garlic oil spray instead. It kills all sorts of pests (one of which is aphids) and also has antibacterial and antifungal properties that will keep harmful diseases away. To make it finely chop three or four cloves of garlic and combine it with two teaspoons of mineral oil. This should be left to sit for 24 hours, after which you should strain it into a gallon of water, then add a teaspoon of liquid dish soap. You should then store the resulting mixture (i.e. in a plastic jug), and use only two tablespoons combined with a full spray bottle of water.
With the garlic oil spray, you should definitely check that it won’t damage your plants before spraying the entirety of your garden with it. Take the solution in the spray bottle and spray it on one leaf of a marijuana plant. Then let it sit for one to two days and return to it to check if there is any leaf damage. If there is (characterized by yellowing), then you should dilute the mixture even more and test the solution on a new leaf each time. Once you successfully have no leaf damage, you can spray the full plant with it – once again, focus especially on the bottom sides of leaves…
