OG Kush Clones

I'm feeling very discouraged with my grow attempts, as I haven't been able to get anything off and running. I know it's a learning process, and that's fine, but I hope to start seeing some results. I know hydro is more complicated and way less forgiving. Recently, I finally figured out that on my first grow attempt, I got some bad root rot, so my subsequent attempts suffered the same demise. I did a purge and a deep clean. I REALLY hope that this attempt can jump off, although I'm already seeing some issues with the leaves. I'm trying to be clean and conservative with my nutes. My goal is stay positive, vigilant, and patient. Special thanks to those of you who have given me some great advice thus far. I'm very anxious about keeping this diary public, as it outlines my mistakes, but hopefully I can learn from them :)
