re: Doc Bud - High Brix Q&A With Pictures
Hey Docbud! Thank you so much for taking your time out to answer my question. I am not 100% certain that it is the moist soil that is killing off the roots but it seems to be that, or like you said, too high of EC for the roots to be there at all, so therefore aren't sucking up the water. I wish I never cancled that order on the soil EC probe and may have to re-order it because I think it would be the magnifying glass to the supersluth as far as showing me the evidence I need to go one way or the other. I will try popping a pot off in a few days when the soil is a little dryer and see what I have going on under the soil. (great idea)
In my mix... a lot of little things... It is mostly promix with about 20% worm castings, and about 20% mix of perlite/pumice with a few cups worth of the amendments (the 6-5-3)azomite, and other things like greensand, lava sand, crab and fish bone meal and kelp meal. For the most part each of those are about 1 cup per ingredient spread across 7x 5 gallon pots worth of the soil base. On past grows I added very little nutrients in my feedings, mostly compost teas and water, but this grow I wanted to see if maybe I wasn't feeding them enough, so I have been doing 1/2 doses of Earthjuice grow and bloom, along with some potassium silicate, cal/mag. I also took your advice of no sugars/molasses so I haven't added any to the soil throughout the grow, except for the very last feeding. I have been doing foilar sprays of 1/2 gallon of r/o water to :10ml of Amaze, 10ml of PGR, 20ml of Carboload (5 sugars for transport) and cold pressed seaweed. (ocassionally adding organic b and fulvic acid at about 10ml each). Also yucca extract is added to both the soil feedings and the foliar feedings. I also have been using TandJ tea, but only using about 1/4 off the biominerals they recommend, and about 1/2 the amount of tea activator.
The PPM's of all of these feedings are way below 500ppm.. I don't check the PH, but generally bubble for 2 days which brings it up to the 6.5 range.
The reason I am leaning towards too much water, or too frequently, or both, is because I have the el-cheepo soil moisture probe which actually seems pretty accurate, and usually the top 1/2 of the pots will be ready for a feeding and reading dry, but the bottom half of the pots always read moist...?? so I still think you may be right about their not being roots down below that layer to soak up the water?
Either way I am in the market for some airpots or fabric pots soon, but they wont be making an appearance until my next available grow. I also tomorrow will be going out to get some smalll 3" fans and putting them in the bottom of my grow area to maybe help dry out the soil a little faster? I am going to have to order that soil probe now...lol...
So if it was too much salt, then I guess a good old flush wouldn't be a bad thing to do... I will check the roots in a few days and then let you know what I find...
Again Doc! I thank you so much for being such a stand up guy, and always helping all of us out. I especially appreciate it since if it wasn't for you, I wouldn't even know what high brix is.. Thanks!
I just checked your journal out after seeing the announcement for the announcement....I'm waiting patiently!
Late flowering, I don't water too much, just try to keep it moist, so I water maybe 3/4 to a gallon at a time. However, my soil doesn't stay soggy at all. I can monsoon them if I need to and it still stays spongy with minimal compaction. Also, are you sure it's moisture in the form of soil retention that's killing the roots, or could it be ergs too high in the lower root zone due to a really hot soil?
What's in your mix?
Yup. That's what I recommend. It's in the "In the Lab Thread" early on. I am right in line with you on the amount of water.
Of course, the very best way to tell if they need water is by weight of the pot. I'm always lifting mine and I just know when they need water.
OK, now that I read this I understand what's going on! I had the same type of trouble with Supersoil.....it was too hot for the roots. They just licked at it and got the nutrition, but they couldn't grow in the lower half of the pot very well because of the extreme salt buildup from the supersoil.
I would venture a guess you've got too much of something in the soil that's hurting the roots, so they simply aren't drawing moisture from the lower part of the pot because there are no roots there! If you can pop one out and check I'll bet that's what is happening.
The wick thing might make a comeback someday Ziggy. I'm really wanting to go to indoor beds, but that would require some construction work to install some french doors that open out, so I can get the beds in and out. I might go for a bottom feed system with a wick instead.
