Hey
@Costanza,
To the end of trying to be helpful, please let me be direct. I swear that's the only reason. It's just more efficient.
That's all I needed to hear. There's your issue. That's a bit aggressive with the additives, my man. Like, that's WAY aggressive. The GeoFlora will do the work. It's one of the best selling organic nutes in the world for a reason. Let it work it's magic would be my suggestion. You're on the right track with letting them go on just the Geo and Ph'ed water. I bet they improve. Additives on top of Geo needs to be sparingly and not constant. Just little boosts, and generally only in bud. They work perfectly in flower if done at the right time. And I have yet to find a plant that doesn't simply love the Geo Veg nutes just by themselves.
What size are your pots? Your 1/3 of a cup feeding volume would be the right amount if you're in threes.
BTW - you are really overdoing the silica and the calmag. It's way not necessary to load them up with silica when the plants ain't gonna even be three feet tall (autos) or even if it's taller (photos). I apply that once a week, and ONLY in veg. It's counterproductive once you hit budding. You've already gotten all the stem strengthening and nutrient transporting capability the product has to offer by the time you end veg. We already talked about the calmag. I can't speak to the other two products you were giving.
I hope some of that is helpful.
