Week 8!
Day 58: 2L (pH6.8) + 1ml CalMag + 1ml PK13-14
Today I learned that CalMag contains about 5% nitrogen. So, her nutrient solution comes down to about a half dose of 5-13-14 with added calcium and magnesium - kinda. More importantly, I assume it thus would be worth trying to abstain from CalMag just before harvest.
Also, she seems thirsty and since her last nutrient solution was a week ago, I figured we might as well try a half dose of PK13-14. I'm aware she's still got the organic feed, but I'm also curious to learn whether this will burn her again - now that she's bulked up. The remainder of the week will probably consist of watering.
Day 59: Still damp
Decided to try and even out the canopy further. Remaining two highest branches have been pulled outward, light has been lowered. While the highest apex still reaches about 900 PPFD - which is more than ideal - the entire canopy now receives on average 600 PPFD, while slightly turning down the light intensity from 85% to about 80%.
Addition: after browsing other diaries; the Northern Light Automatic strain information pages on Growdiaries.com, and RoyalQueenSeeds.com, I noticed that about 10 weeks after germination is her expected harvest time. That's one week out!
I'll thus dial down on the nutrition and keep an extra eye on her water consumption. About half of her pistils are still white. If those start to turn rusty and her water consumption slows down, I assume her leaves will also start going yellow.
With the nutrition solution of yesterday she should hold out until harvest, so any leaves turning yellow this week won't be caused by a deficiency, I assume.
Day 62: Soil is dry but cool to the touch, no water
Nothing much going on currently. She's done most of her bulking I assume. While the soil is dry, she's not showing signs of thirst so I'll water her tomorrow. I'm curious whether watering will increase the bud size.
Day 63: 2L (pH6.5) bottom water.
Opened up the tent about an hour before lights-on to water her with 2L tapwater pH-ed at 6.5. Instead of the regular top watering, I gave her a royal gulp on the soil and poured the rest in her runoff tray.
Day 64: Humid, no water.
Some extra defoliation of withered leaves. She won't be needing those as we're nearing the last week. There's the sporadic amber coloured trichome here and there. I've picked up advice saying that, when in doubt, you should give her another week or so and check again. Enjoy the last picture of this week, the money shot!
