I wouldn't sweat it. The first grow is a learning experience. As long as your yield is worth more than the electricity bill you still come out ahead. My 2nd group of plants looks unreal right now after all the stuff I learned from the other plants:. Everything you've learned will show up in future grows. Plants look good and you can't ask for much more than that. I've heard first grow horror stories lol, I'd say this has been quite successful sofar.
