Sorry to hear about the attrition of forces, Nosias! The yellow leaves do make it look like the same sort of pH/coco buffering issues I had on my first attempt. Careful pH control and buffering with cal-mag fixed it for me. I'm sure you'll get it sorted and the remaining girls will reward you for it! I'm using my syringes all the time for measuring and I really recommend getting a decent ph meter. I can't imagine doing hydroponics without that tool, now that I own one.
Bummer about the overcast conditions at the eclipse too! It was only a partial eclipse here but it looked cool for a few minutes before the clouds rolled in. Talk about stoned stoners, here's a photo I took with the protective film the wrong way by accident!
