heat and calmag . Brown spots usually lack of calmag or locked out plant . Curling leaves taco in usually heat . All other tents are good interesting . Can we see the other plants as well. Do they also have the leaf curling ? EDITED LIGHT . to much . With led lights to cause taco
Annoyingly this forum is selective in which images it will allow me to upload, I've attached the ones it will let me. I suspect light is a little much, it's on its lowest and I've run out of head room :/
I'm feeding them 1000ppm, twice a day to run off Which roughly breaks down to 600calmag 300 a+b canna Coco base 100-150 PK13/14 PH 5.8-6.2 Wondering if I caused Calmag lockout by hitting her with PK13/14
High P will lock it out . Just back off a bit and add calmag it will correct itself soon . No worries you will be able to harvest them when there done Not that bad
PK 13-14 is meant to be used at a very specific time and only for a week. I don't think it's necessary at all, just check what's going on with your runoff and adjust base A + B accordingly. 600 ppm of Calmag why!? that's a lot of calmag might wanna follow instructions on label.
I'm using tap water mixed with dehumidifier water (basically RO), so around 300ppm is tap (I have v hard water 500ppm), I'm calling that calmag, tho it's a mix of junk no doubt. 10L res starting at 300ppm 20ml calmag 25ml A canna coco 25ml B canna coco 5ml Rizotonic 15ml canazyme 25ml boost 10ml pk13/14 Only variable which changed was the pk13/14, I'll cut that shit out now, thanks for confirming
Also, using strong Led types of light, HLG's engineers explains that raising soil-media temps also helps with calmag def associated with light stress.
