just looked at the sick mommies. you'll get them back don't worry. I grow organic and I never worry about ph, WHAT? you may say. but if your soil has the proper microbial life ph will regulate it's self. Right now I use advanced nutrients and I put a major emphasis on the fuzzy roots package available from discountan.com. And it's not that the ph regulates itself but the microbes that take care of this. As long as they are there they convert the nutrients to the readily available forms and pass it along to the roots. They have a symbiotic relationship that has been there for millions of years. check out that package it will make a difference. Another company called humbolt nutrients( I wonder what these were developed for...ha) has a similar line of products I'm going to try them out after I run out of my advanced nutrients. I promise I'm not just some kook coming out of the woodwork. I've had practical experience and plenty of failure to learn from. just give it a shot the microbes will make your life alot easier.
