PC, thanks a bunch for the info. Weird. CNS17 isn't listed on their web site as one of the products that botanicare makes, but everybody that sells it says it's by botanicare. The exception is this place CNS17 that says that some dude made it:

Dr. Lynette Morgan is an internationally accomplished hydroponics consultant, researcher and author who recently formulated the Commercial Nutrient System: a professional-grade fertilization program consisting of CSN17 Bloom (2-2-5) & Grow (3-2-4). Each component is highly-concentrated with chelates and the essential elements plants require to reach their full potential. CNS17 Bloom & Grow are suited for any plant, in any medium however they are designed to equalize increased levels of potassium found in some coir-based medium.

I'm guessing some old dude made it and American Agritech, which makes Botanicare bought the rights and say it's theirs. Anyway it sounds like good stuff and I wanted to try some bloom since I just switched schedules but not food. I can't find any in stores around here with the little amount of looking I've done so far. Oh well, maybe that one that's more than an hour drive each way.

The only filters I've been using is a fairly large mesh at the funnel, and a common garden hose filter at my quick connect. My pumps are barely big enough to deliver a good spraying, with 16 nozzles each, veg and bud. And after 3 grows some nozzles are completely clogged. I don't want to take my system apart every grow to clean nozzles. Hell, I might as well go back to DWC. I'm afraid to get the mist I want, I'll have to switch to smaller nozzles, get a triple filtration system, and larger pumps to squeeze the solution through the fine mesh.

The Liquid Karma guys claim that you can use it in hydroponics, and even aeroponics if you use a pump sock. Cha yeah, right. Have they seen the thousands of various size chunks in that stuff? It settles in one minute. I bought pump socks, and I'm sure they will help, but I doubt very much they would keep the nozzles from clogging. No, I think the solution here is to get 100% water soluble nutrients and additives.

Thanks again for the heads up PC.
