Anyone used Nature's Living Soil and found rust-looking spotting?

Keep in mind, unless the people doing your test know you're trying to maximize a cannabis grow, the 'optimum' levels may or may not be what you want. In other words, according to the test your Ca may be high, but high compared to what? Are they suggesting in the test that the 'optimal' levels are for cannabis, for your lawn, for a vegetable garden, or? I would take it all with a grain of salt and just keep an eye on your girls. They'll tell you what they want. Good luck.

I'm curious about where to even find the optimal levels for cannabis. I've searched and everything I've found just seems to provide optimal PPM levels of the overall solution, not the individual minerals that make the solution.

I couldn't tell you that either friend. I suppose in time, with the legal states growing, it will be determined, if it hasn't already. I just saw a youtube video by a Dr. Bruce Bugbee, which sort of took on this subject. You may find it enjoyable to watch. Good luck.

After you flushed did you allow to dry or amend right away?

I would have allowed the soil to dry out and then amend accordingly.

I’m still struggling with dry amendments I always end up using GH to finish. I’m thinking of just using GH for entire grow

I think this is a very salient point. For the purposes of their analysis, I chose "vegetable garden". They had different options. Thus, we can guesstimate that we are roughly in the ballpark of cannabis, albeit with some uncertainty.

I flushed and then added Build-A-Flower (.5", maybe?) top-dressing before watering in one last half-gallon. I haven't heard of allowing the soil to dry out before re-amending, but that seems a little counter-intuitive to me, given that we're dealing with organics only here. What do I know though - I come from the slow, but vital, world of cacti

I agree with others above, that it's about time we have more precise numbers, so that tests like this could be more useful. I understand that Build-A-Soil has its own proprietary screening it will do for $70, tailored specific to cannabis. But I'm cheap! Besides, this info should be more publicly available, if certain cultivators are already working with it...

EDIT: Spelling.

There are folks using NLS products that are having virtually the same issues with their grows me included. Original blend and autoflower blend show the same issues. Usually a couple of weeks into flower (autos). Brown spotting on the leaves, yellowing leaves, etc. In my case being a newbie I thought I have Cal/Mag deficiency and added some. No fix. Added higher phosphourus amendments but was too late. Thanks a bunch for posting that soil analysis (I shared some of it with others who were/are having issues with their NLS soils). A member on another site posted an analysis report on straight FFOF soil to compare with your info of the NLS amended soil. Pretty evident that the NLS is problematic. Enough so that I am going to be using different soil mixtures without NLS products on future grows. I'll use my remaining NLS products in my yard plants or use it to make compost teas.
