Maybe you use hard tap water? I've always seen that calmag is a requirement for coco and that typically calcium and magnesium are the most common issues. I'll let you know how it goes
My light is about 12 to 13 inches away, mars hydro ts1000, thats the recommended height for flower. But I could move it back a little
I've veen using GH Flora with tap water. I feed 5x per day with an automatic system with a halo. I usually do a flush ever week or two
I have a cannabis plant in coco coir. Feed ec has been 1450 to 1550 and run off ec has been consistently low for about a week at 1250. My plant is in week 3 of flowering. I supplement with 3.75ml/gal of calmag and ensure my feed ec has a ph between 5.8 and 6.2. Now my plant is showing odd...
I'm using the GH flora series light feed schedule. I'm on week 2 of flower. I already use 2.5ml/gal of calmag. And my input ph is always between 5.8 and 6.2 and my run off ph has been around 6.1 consistently. I fertilize twice a day with at least 20% runoff. Conditions are usually 65 to 80...
Title mostly says it all. But I'm growing in coco. I've never had a strain this picky. But the past week or so run off EC has been lower than input. I've been at 1.2 input and getting about 1 to 1.1 run off. I've had issues with this plant when input EC is too high so I'm hesitant to raise input...
Well I meant 1.65 was the feed EC with is around 800 ppm. But that is also the recommended "light feed" amount from GH. But others here, as well as cocoforcannabis (my primary source) say 1.2 EC is more typical.
Flushing, lowering EC to 1.2 and lowering calmag to 2.5ml/gal is my game plan
Correct, I meant EC 1.65
And you're probably correct. I've read that as long as EC runoff wasn't over .3 above the feed EC then everything was okay. So that was my reasoning.
But your solution makes sense. I will flush and lower feed EC to 1.2 and monitor.
I should've known this could be the...
I feed twice a day and usually ensure adequate run off.
What's your reasoning behind the lower ph and EC recommendations?
And thank you btw for your help
I've had this issue since they were a seedling. Discolored leaves and eventually some brown spotting. Usually affecting top growth. I'm growing in coco using GH Flora series using their light feed schedule. I'm on week 4, been feeding an EC of about 1650 with PH of about 6.0 to 6.1. Most recent...
I'm using GH Flora series with their "light" feed schedule. Currently starting week 3. EC has been around 1.2. Including 5ml p/gal of calmag since I'm growing in coco. PH always between 5.8 and 6.2. Fertilizing twice a day. Been seeing this issue for about a week and it's getting worse. I...
It's def too big for the tent haha. But this was an autoflower so I didn't have much choice with veg time. I thought autos would be smaller haha. And this all started a couple weeks ago. It may have something to do with my new automatic watering system but I'm pretty good about checking the ec...
My light has a dimmer switch that may be useful for that. I also know there are some phone apps that can measure the light intensity but not sure of they are recommended
