Plants are doing well. Watering roughly once weekly continues to be the current schedule. In this week's watering (week 6, Thursday), a nutrient mix was added (19% Nitrogen, 5% Phosphate, 20% K2O). pH was measured (via the runoff/drainage water collected) on all three plants using a pH probe, of which was measured to be slightly acidic for all plants (exact pH numbers above in the photo descriptions). We are aiming for a pH range of 6.0-7.0, so in next week's watering, we will add a buffer solution to alkalize the soil. All three plants lower branches were also pruned.
