They look like aphids. Normally you can just hose them off with some soapy water, in bud just rinse them off. A lot of my sparkle autos were mutants. I had one that looked normal all through bud until the end and then it got weird. The bud was fluffy and airy and the caterpillars loved that. They flocked to that plant and didn’t touch the others beside it. I haven’t had much success with any of the dark spark lines outside. I truly think they have been bred for indoor and microgrows.
btw… I know everyone says to germ autos in their final pots. I haven’t done it yet and it has not been a problem at all! I usually transplant them from starter to final at 10 days from germ. I have some fabulous looking autos out there too. As long as you don’t do it too late, they won’t skip a beat.
