Ec stengh through plant stages

[MarkBrandonRead]

So I found this image online showing the different ec readings for different plant stages here is the text from the site I spotted it on

An indicative EC range for cannabis plants is 0.8-1.3 for seedlings; 0.5-1.3 for clones; 1.3-1.7 under vegetative phase; 1.2-2 during flowering. Different varieties of cannabis might require significantly different values of EC.

would everybody agree to this to a degree and also please state what you all use and what medium if you will

I grow in 50/50 coco/perlite. I start 0.4 for seedlings;1.1-1.3 in veg, and 1.2-1.3 in flower. This is what the cultivars I grow tell me in the environment I grow in. If I were running stronger lights, then I would likely need to push them harder. If you're in something like coco and doing high-frequency fertigation, then the outflow EC will tell you what modifications you need to make.

Thanks for the input I've got these things called blumat drippers that water based on the moisture level so they constantly get feed and water when needed I was planning on hand watering every 3 days to get run off do you think with this kind of setup I should feed at half the normal strength seen as it can access the notes and water when it likes

Your nute EC will be very different if hand "watering" or using the blumats
About 1/4 of your normal drain-to-waste EC is what Sustainable Village recommends if running nutes through blumats

Thank you much appreciated

also your EC requirements will be different depending on the age of the plants.

For example a 4 weeks veg going into flower needs less EC than a 10 week veg going into flower due to being a bigger plant etc.


environment also plays a role in how high an EC

High temps and low RH means plants will need a lower EC to cope with the higher temps etc.


lower temps and higher RH can usually handle higher EC.

as @Billy the Mountain has mentioned the system you use also dictates the EC strength.
