GG #4, 3rd Auto run. (cropking seeds)

I also use Remo nutrients, I tend to feed trace amounts in the first two weeks, then slowly amp it up to what the chart recommends. Hope it helps, Cheers :)

Also while your plants are that small they won't need any nutes yet in soil.

Just give plain water next then build up to the remo chart. I find with autoflower plants you don't need to use as much.

Any photos of the leaves or bug?? Would make helping you and giving an opinion easier.

Spray him with a mixture of dawn soap and water and see if he dies. If not the spray should kill any eggs that you spray. Won't hurt your plants spraying them. Just do it at lights out. It won't kill potatoes bugs but it does do a number on their eggs. Cheers

I have never had them in my grow before. Have you got them yellow sticky insect traps. If so put a few of them up. You will be able to see how many pests you have and what they are when they stick to the trap. Someone else on here might have had same problem and be able to help out more.
