Greetings from Arctic Central Minnesota where we are finally allowed to legally grow our own cannabis!
I'll try to keep this short and sweet! I have these four blueberry muffins from Humboldt seed company very late in flower. We have a lot of milky trichomes, no Amber yet but I would say one week max till chop. We are at day 40 flower right now, but the pictures I'm posting are from day 35 although not much has changed. HSC says 45 days strain but from what I've gathered it's usually around 50.
This strain has been a pleasure to grow but I have some concerns about possible excess nitrogen in two of the phenos. Numbers 2 and 3 still have dark green foliage and show no signs of fade / yellowing on lower older leaves.
Here's a picture with different lighting for perspective:
Coco in 3 gallon fabric pots, 2 Mars sp-3000's and about 60% (30ish DLI) R.O water, GH flora trio, Humic/fulvic, rhizo, yucca, mag sulfate and bacillus. Fertigate 3x/day til run off. 350- 450ppm avg through veg and mid flower. Loosely following the cocoforcannabis feed chart with some tweaks. Began tapering Cal mag and micro after stretch, roughly day 14F to about 40% strength, and for the last 2 weeks only been running 1 ml/gal micro and 1.5ml 1-0-0 calmag. EC has been under 200 PPM for the last week and run off is coming out under 300 ppm. I got a little frisky with the lights late in veg and early flower but dialed them way back by week 2F after I noticed UV damage on number four and bleaching on number one. If I understand correctly this probably contributed to excess nitrogen uptake leading to my current problems.
These girls have one week left tops, and I've basically cut all nitrogen minus the tiny bit in calmag and micro, But I'm still not seeing that dark green foliage lighten up or any kind of fade. They are still getting p and k at normal dose.
Looking for advice on what to do here since I'm running out of time.
Would I be wise to start a flush with cal mag'd r.o at super low ppm, like 100? They're currently getting about 275 PPM made of 1.5 ml calmag (1%N), 1ml micro (5%N), and 3ml 0-5-4 bloom, But even at that level I'm worried they're getting too much nitrogen.
Please note that number four has UV damage from earlier in flower and is not nutrient related. #1 I suspect has some light bleaching from before I dialed the lights back.
Would love some guidance to save me from ending up with some snickle Fritz!
I will humbly obey the orders of more experienced cultivators than myself, Just take the wheel and steer me and my four ladies to Glory!
Thanks guys and gals, and happy holidays!
