Week 7 – Day 51 Flower Day 21 🔄 Looking back: A calm and steady week – mostly just watering, observing, and removing an occasional leaf 🍃 Stretch seems to be slowing down now. Vertical space is getting tight, but still manageable 😅 🌱 Mimosa Evo – Growth & Nutrients 📏 She hit the 100 cm mark this week – tallest plant in the tent! 🏆 💧 Drain pH is 5.9, even though she receives the same nutrient mix as White Widow. ⚗️ Feeding at 85% of the Advanced Nutrients Masterline schedule 🤷‍♂️ Not sure why she buffers pH better – but she’s clearly thriving! pH & Soil Compatibility Insight One thing I've noticed: it’s really hard to raise the drain pH when using BioBizz Light Mix together with Advanced Nutrients. After some research, this might be due to the way BioBizz buffers pH – using microbes instead of lime (like in Plagron or Canna substrates). Plus, I’m feeding those microbes with Bud Candy, which might lower the pH even further. 💡 If you're using Advanced Nutrients, you might get more stable pH results with soils like Plagron Growmix or Canna Terra Professional, which use dolomite lime.
