Smart thinking to adapt the dosage. That's awesome when you spotted the deficiency and added cal/mag, it solved the issue! I love when that happens. That buffer layer is a great idea... nice to give it a safety net and also reduce stress whenever possible. If I were using it, I would probably use the buffer layer on the bottom but also mix it in to the upper substrate...but I grow organic so inert just doesn't sit well with me lol. Definitely need a whole lotta love! The key ingredient !Good question : from the start I knew the AB wouldn't eat much, so I adapted the dosage and I gave 1/4 th of the quantity ( yes, 1/4 th )
I used Advanced Nutrients Grow A/B with Sensyzim, and then Bloom A/B with Sensyzim and a pinch of bud candy. It's a rip off, but that's not the point of this thread
At one point I suspected a deficiency but I simply added a bit of CalMag ( as my water here is very/too soft ) as I thought the plant might not synthesize/absorb enough out of the given dose.
And that was enough.
For the light, it was 13 hours of darkness in flo, and absolute obscurity.
The soil was made of this
it has no added nutrient with a high level of calcium
and at the bottom, we have put a 2 cm layer of
Special Mix | Gold Label
so that when the plants grew, it can reach that layer and act as a kind of nutrient buffer, in case we wouldn't give enough
For the rest, a lot of love
