Jungle is growing on top of my washing machine! On the last day of week 6 I lowered lights to 35cm from canopy, this week I’m going to monitor that number and adjust as necessary because the plant is still in stretching + bud setting phase.
I’m feeding with high N+mag and I’ll continue until growth slows down, than I’ll switch to megacrop 2parts. I expect that to happen end of this week, 10 days max.
Day 42 - changed the fan
Day 44 - finally installed the blumat auto irrigation system. It wasn’t that easy since branches are really near the substrate but at least I had the carrot already placed so I was able to do it.
High frequency fertigation on coco is a must, you can’t take advantage on coco great qualities watering 1 or 2 times a day. My system has 5 drippers placed in a Pac-Man shape, more or less.
Day 45 - This is an important day since it marks the halfway point of this crop, based on my previous results. Coincidentally I’ve also spotted few small trichomes on a leaf, I guess the plant is now ready to build up mass and flavors. I did a minor defoliation to open up the inner canopy and to get rid of some plant’s nitrogen reserve.
I prepared 20L of my bloom solution and mixed that with the veg solution in the reservoir. For a week I’m going to use this transitional feeding. Lots of sulfur, seems to be on a volcano 🤣
Day 46 - spotted a minor P deficiency. There is probably too much calcium in my solution that is antagonizing P absorption.
I mixed another batch, this is the ppm breakdown
N 100
P 100
K 280
Mg 85
Ca 150
Before I had P 40 and Ca ~190, my tap water has 80ppm of Ca that is already counted it.
I’ll keep this value for a couple of weeks than I’ll lower everything except K.
(Edit from the future - K is too high)
Day 47 - plant looks happy and bigger, it drunk 3+ liters yesterday.
There is no need for humidifier anymore so I’m getting rid of it. Temperature is 30-32C with 50-60% humidity.
Day 48 - buds are swelling, some branches are already showing the spiral structure. Plant drunk 5 liters yesterday, impressive.
