UB,
I'll be sending a sample of my compost to the local extension office to be analyzed as soon as its ready. They do a comparative analysis of the soil/compost and the need of a chosen plant included recommended feeding schedules, etc. I can't very well ask for an analysis for MJ. So what plant, that one would grow in SE US, has a grow cycle and nutritional needs similar to MJ.
Just list vegetables. If you need to be specific, tomatoes. I just received a report on 2 samples and on one I listed two crops for the field, the other my vegetable garden. Be sure and send off a representative sample of your final mix. TX A&M soil/water test lab charges only $15 and you get your NPK and other macros (Ca, S, and Mg), micros, conductivity, pH, as well as recommendations of what to add. Save on postage, and send off a water sample for analysis too. You can use a 12 oz bottle.
Based on one soil sample, I put out a 150 lbs. of a 18-11-5 with Zn and Fe yesterday, and now we have a nice slow rain going on.
BTW, I bought 250 lbs. of high grade fertilizer
for $52 total from a feed store. Called up the manufacturing plant's agronomist (yes, a legitimate doctorate) and talked with him about a few issues, and went about my business. The N sources of this food are ammoniacal, just what I want to get a little pH reduction with very little leaching. IOW, you can get very good professional advice and cheap but high quality products if you do your homework. Stick with the professionals in the horticultural industry.
UB,
I just spent the last 6 hours reading this entire thread. I am very impressed by your logic and thinking when it comes to MJ. I've spent countless hours on RIU learning from others, but your approach is refreshing. This thread has really opened my eyes about nutes and the general lack of N. I had no idea what i've been doing to my plants. talk about a wake up call.
6 hours, wow! Welcome to the thread. I'm glad to present a different approach. Others contribute some pearls of wisdom too.
I like your opinion on this so called "green" movement. I think all the propaganda has helped turn the organic movement into the common misconception that it is today. I always believed they were right and i was "cheating" by using chem. Now i know.
They are not well meaning. It has become a cult based on feelings, control, and ideology.
I was also unaware about what FF and AN were really doing with their line of products. this whole marketing thingie is a trip. i 100% fell for it.
Alot do. Check this out if you want a real laugh.

I had no idea flushing was so counter intuitive. the part that stuck with me was "A plant isn't like a radiator, nothing is flushed out. Use judicious foods until harvest to maintain the health of the leaves, don't worry about bud production, forget the bud." its amazing to me how many people think they understand this art...
I'm not the be-all of gardening, I have alot to learn but when you understand that alot of salts are broken down into their respective ions BEFORE being taken within plant tissue, you must question such forum paradigms.
Just wanted to let you know how much i appreciate and respect your hard work.
Thank you!
a great number of the people asking questions on here shouldve just read the damn thread. that's why great dudes like UB spend so much time writing them, so you can READ and LEARN from them. not so you can ask the same "why are my leafs fucked up" questions over and over again (no disrespect, i've been there but damn!)
Go to Advanced, someone has just posted another "NPK help please".
Good luck,
UB
