Week 7 – Day 51 (BT27)
A quiet week for RedPure#4 – mostly just watering, observing, and removing an occasional leaf 🍃
The stretch seems to be coming to an end. Height is stable at 40 cm, and space is still manageable 😅
Her buds continue to swell and look very promising 🍇
However, the drain pH remains low at 5.7, which might explain some of the issues she’s showing.
After some digging, I suspect the combination of BioBizz soil and Advanced Nutrients is the cause.
BioBizz relies on microbes for pH buffering, unlike Plagron or Canna, which use dolomite lime.
On top of that, I’m feeding the microbes with Bud Candy – which likely lowers the pH even further 🔬
📌 Takeaway: If you're using Advanced Nutrients, a substrate like Plagron Growmix or Canna Terra might be more compatible.
With BioBizz, the pH in runoff stays constantly low despite using water with pH 6.6.
RedPure remains the most sensitive strain in the tent – but also one of the most aromatic 🌸💜
