    Week 6 of flower. Please help :)

    I wasn't paying close enough attention and barely noticed this on many of my leaves. I'm in week 6 of flower and have had smooth sailing until now. I'm leaning towards calcium deficiency. I use coco and supplement with 2.5ml a gallon of calmag. Other than that I'm using the gh flora series

    Optimum Nutrient Levels for Cannabis. A Scientific Study

    A scientific study was published in November 2021 about the optimum amount of nutrients for Cannabis.

    What water reservoir you use?

    Just got my Octopot system and I need to supply my own reservoir. Was looking at drums, totes, collapsible reservoirs, etc. and am leaning towards a heavy duty black tote that I will paint white on the outside. This is to maintain temps and help prevent algae growth. Before I make the purchase...

    Fan Leaves Yellowing, One Cola Looks Burned, Week 7 of Flower

    I'm wondering if this is from nutrient burn? The ppm was increased slightly from 550 to 650 (baseline of well water is 200 ppm). I wouldn't think that wouldve had such a big effect. They have been happy around 500-550 ppm (currently at 500 ppm)...See photos below:

    Can I use a 20-20-20 instead of a 20-10-20

    As Dr. Bruce Bugbee suggests, they use a NPK 20-10-20. Unfortunately I can't easily find it (I've tried online and in some shops), but I found a very good 20-20-20. May I use a 20-20-20 instead of a 20-10-20?
