I remember you telling me about recycle sil. I have actually have it noted in my nute section of my cultivation notes. Idk why I thought it was something you add when recharging the soil (during winter months for example) probs because that was what I was talking about when you mentioned it LOL. I will have to see if I can find it on the 'zon
The build a bloom product could be of interest. My only concern here is that I read on some product site (I think it was one of the many Humboldt nute sites) that you have to be careful what they are using for chelation.
If you want organic silica - there are options
Pro-tekt -
Potassium (K2O)……….3.7%
Silicate (SiO2)……….7.8%
Derived from potassium silicate.
You can look for horsetail fern and harvest and make a tea with it. It's very high in Silica. Plants love it and totally organic.
The cal/mag stuff.... meh. I'm an organic farmer and I do not use any of that stuff. It messes with the microbial community. Best option for cal/mag is to be sure those elements are in the soil in a sufficient quantity. You wont have a need for a bottle of it.
Pro-tekt is one of 2 bottled stuff I use.
The other is Ful-power - fulvic acid and its organic.
Pro-tekt - a quart lasted me like 4 years
Ful-power I use a lot as well and it lasts a year-ish.
Can foliar these two on and/or water in.
