Gelbe Plätter bei Jungpflanzen

First of all, its an Auto, they tend to do weird stuff. If you want reliable genetics, get a Photo plant. But I cant tell what your light is set to even with the pic of the knob, I cant see if its 100% or 60%, but for seedlings this young, Id be running it at 20% and about 12-18 inches from the plant for the first week to 10 days. After that go to 50% light at same height. But Id consider getting some Photo plants if you want to actually pull in a decent harvest and not stuff around with Autos that just have issues all the time. Most people consider 6 oz from an Auto a win, I consider anything less than 6 oz in a photo a failure. Are you growing for fun and for insta pics or are you growing so u dont have to ever buy weed again? If its the first, stick with Autos for the fun. If you want to grow enough weed to have more than you will ever need, grow photos. I grow Photos and average 8+ oz inside per plant. And my seeds cost the same as yours, im just using alot less of them to grow alot more weed than you are my friend. So please ditch these Autos and come to the Photo side. We want you to have lots of weed like we all do. 😉
