Good morning Gee hope your weekend is going to be awesome.
I have a question about clones and soil lol. So I know that you have run your Durban in specific soil that helps push the Brix higher. I took a clone of that plant I'm growing that's able to push into the 20's.
My question is what can/should I do to preserve that "Mother" plants soil? Is there anything I can do to push the clone higher into the 20's? I really just want to see how high her threshold is haha.
Well if light and minerals are adequate, and you water correctly, and your environment is good, brix comes down to the 5 things.
Carbon Oxygen, Calcium, Phosphorus, and microbes.
Your soil is solid or you wouldn't have got near 20, so I'm leaning in a couple directions.
One is that you are battling calcium right now, as in having to add dolo-water, so you could have added more to your mix at cooking. That will increase brix.
The other is microbes. Obviously your mix is quite balanced or you wouldn't have brixxed that high, and calcium can be easily maintained thru dolo-water, but you may have room to increase microbial activity to create more food and more humates, which move your minerals. So a compost or EWC tea and a myco drench can't hurt. Don't make the tea a feed, just EWC and molasses, and myself I like to add kelp meal, but it's not nescessary.
It gets tricky around 20 because it's hard to get improvement when you are close to the top. It could also be that your pheno just isn't capable of more, but that doesn't mean you shouldn't try.
P is the big one. If you dump too much in myco rebels and it goes bad quick, and if you add just a smidge more it takes a couple weeks to show improvement.
So you are best to have it always available right from day 1, and as the plant grows it can stay caught up, or even a bit ahead, on P. The plant needs a smidge more P every day, than it needed the day before, simply because it's bigger today than it was yesterday. Even in flower it still puts on weight. Having myco well established early also really helps, so some successful used soil is always a good myco/microbe innoculant for a mix.
My thoughts on Gaia was that it was fantastic, but a bit light on P, so if you have some bone meal or high P bat guano available, I would add a bit of that to the mix. Even in veg.
Lol, this winking face reminds me of how I felt last night. I went out with a few women to a wine tasting and I was absent mindedly examining the goings on and my eyes settled for a brief moment on a man in conversation. He noticed I was watching and he looked my way and winked at me. I tried to return the wink and it felt like this lol, like a lopsided gimp with my tongue hanging out. Remind me to never try to wink at anyone ever again 
It was a gorgeous day today!
