Hey buddy, apologies for not stopping in for a while. I've pulled up a seat on your new journal. Caught up with this one 2 finally...
I've grown a few auto's which came out very similar to your buds, still great quality I will add, so don't be hard on yourself.
I'm an experienced led grower. Let me tell you, do not worry about what Johnson say about their led, my advice is to try it further away, not closer!
I'm convinced a plant can become very unhappy with an led too close. I'm vegging with mine 5ft away and getting faster growth. The led companies just tell where it needs to be to achieve the figures they wrote in their sales speel. Trust me the plant always feels different about it. Do you like it when somebody pushes you to your maximum level constantly? I doubt it, just like plants we becomes stressed and require more rest to recover!
You are better of having the led really far away, if the plants stretches too much, drop it slightly until it's perfect, then remember that distance.
Imo whether it's cmh or led try them further away. I noticed in a few pics some of the leaves high up looked toasted. Good in a way though as it hasn't bleached the buds like many leds do. I will yield more with an led 4ft away - than I will 2ft away!
