So, I got these plants.... Coco, using Canna A+B nutes. I started them July 1. Now they all look pretty sick. Brownish yellowish spots, bottom leaves are wilting away. What do I do?? Thanks in advance.

No ideas? Does it look really bad? This is my first grow and everything is going very well until now.

What's your pH? What kind of water are you using?

Did the problem first appear at the top or at the bottom of the plant?

If it started at the top, it's manganese deficiency, easily fixable with 2 tbs/gal molasses.

If it started at the bottom, then it's nutrient lock caused by high/low pH.
