I think your plants look great, and the final weeks of flowering really add weight and volume to your harvest, so just be patient and I'm sure you'll be satisfied with your first harvest. After all.. there are plenty of people out there who do not end up with something as good as you have on their first attempt... keep with it and you'll get better and better. I think its good to pick a strain you like and grow it out a few different times, trying different methods, before you rule it out as a weak yielder or something. Certain seemingly minor changes can cause large, positive reactions by your plants.

I do agree that nutes would be a great addition to your grow, even if it was some FF Beastie bloom in the last few weeks before you flush.

Just remember... even if your harvest isn't completely up to its maximum potential... there is still value in the lessons you've learned along the way, so don't be disappointed.
