Hi guys. I’m a littel worried that they are very...

This reminds me of my Tangerine Dream grow... it was a jungle just like what I'm seeing in your grow! There are those who will say defoliation is not good for plants but defoliation is absolutely necessary in some instances and I'd say this is one of them! The problems you're going to face are lack of air flow which could lead to bud rot, small popcorn buds underneath because they're just not getting the light they need and, as with my Tangerine Dream, the need to try to keep the plants going through several harvests because the buds underneath aren't going to be anywhere near ready for harvest when the buds on top are - and with autos, keeping them going is a bit of a problem because they're programmed to end their life at a certain time. If this were my grow, I would be getting in with my trim scissors and removing large fan leaves that are blocking the light - but NOT doing it all at once since it will be stressful to the plant. I'd try to get 1/4-1/3 of them the first go round (target leaves that are growing towards the center), give it a rest for 3 or 4 days and then get in and do more as you see fit. Marvelous grow... you've done a great job! Good luck!
