EC Drop, Early Water Swap & One-Handed SCROG Struggles
Another week down in the HOMEbox and things are actually starting to roll along, despite my best efforts to complicate things. Here is how the last few days played out.
From Sunday through the rest of the week, I only had to make a few minor adjustments to keep the pH between 5.6 and 5.8. Plus I almost forgot to switch the ph-downs. Canna has two options for that, one for veg and one for flower. Don’t know if it’s actually necessary at this stage, but since I already have both, I might as well use them as intended.
On Tuesday, I noticed the EC value had dropped, which always means active nutrient uptake and that is a sight for sore eyes.
By Wednesday, the EC had fallen from the initial 2.1 down to just under 1.9. Since there were only a few liters left in both buckets anyway, I moved the water change forward and filled each bucket with 15 liters of fresh 2.1 EC nutrient solution. I set the pH to 5.7 at this point and it has nearly been holding steady ever since, requiring only a few minor tweaks and nothing too dramatic.
On Friday, I installed a ScrOG net to use the space inside the grow box a bit more efficiently. The distance from the canopy to the light is 40 cm, which is about 15.7 inches for my imperial friends, and running at 50% power puts the PPFD right at 700. If the stretch hits the way I expect it to, I will likely need to increase both the light distance and the power later on, but we will see how that goes since I really want to avoid temperature stress.
By the way, did I mention how utterly miserable it is to install a SCROG net using only one hand?
Today, I kept working on tucking and weaving the branches through the SCROG net to get everything properly laid out. Pre-flowers are still playing hide and seek with no signs visible just yet. Let us see what the coming week brings.
