Hi everyone, I grow for 4 now years using bio bizz products with bad and good results. It is all technic you using and the knowledge of stuff that you are using.
Only some a year ago (I want to think) I manage to find the sweet spot so I thought that I'm going to share my observations with you guys.
I use bio bizz all mix soil with bio bizz grow,bloom,top max and alga mic. In addition I use dolomite lime, Rizotonic, cal mag (because of LED lights)bio silicone, Epsom salts and I am trying also PK 13/14 (new thing for me)
So, it looks that in bio bizz all mix soil there is enough food to get you going for at least 35-40 days (so through the whole vegetative stage). Uill then I was using only Rizotonic combine with cal mag (2ml of Rizotonic , 1.5ml of cal mag a litre of water) and my plants are green and healthy. In week 4 give 1/4 of tea spoon of Epsom and that seems to stop possible Mg def.
Autoflowers are sensitive to nutrients and don't need as much as the photoperiod plants, so always I am using like half recommended dose (apart for cal mag which is going in full dose)
Alga mic in combination with Epsom salts makes brilliant foliar feed which is absorbed by leaves way faster than through roots, so if it happens you run into cal mag deficiency just do that (I use half of recommended dose of alga mic and 1/4 tee spoon of Epsom salts a litre of water and plants are loving it)
Dolomite lime seems to keep PH of soil at the bay and supply some extra Ca to the soil so it is good stuff, (I use table spoon mixed in the middle of 10l air pot and the same dose on top)
In the flower you need to pay attantion to the color of leaves it is very important because the plant used up by now most of nutrients in soil, and any weird things happening ( like clawing, dark green color of leaves) you need to back off with the feed otherwise you might have some lock out of nuts in the soil and might end up flushing your lady which because the stres will cost you yeald wise. If you see signs of under feeding you need give it a bit more nutrients but remember you always can give more food but you can't easily take it away as it is already in the soil, so always play safe
Hope I didn't omit anything and good luck, bio bizz products are awesome but you need to know how to use it (I am still experimenting with it)
Peace brothers
