This thread started out because my runoff was strikingly low .4 ec instead of 1.4 Ec. So was the feeding frequency and volume of feed. I am sure my runoff would be normal like .3-.5 EC higher than inflow if I checked right now.
I wait until issues show in leaves before changing anything but should not have to, was under impression that is how coco is. I know you advocate for runoff, you are one of the few that do.
What could happen in veg that causes any issues with low runoff ec? Why would a flowering plant suddenly stop uptaking food?
Everything is readily available to the plant I thought. Something horribly wrong would have to be happening to not uptake nutes suddenly.
My apologies buddy idk how i missed this?
I can't think why a healthy flowering plant would stop taking up nutrients I've never encountered that before?
When you say taking up food you mean the volume?
Low ec in veg i have had when using led in cooler temperatures, it was pretty cool circa 20c iirc and no matter how many times I fed the run off ec was always 50%± down iirc (I've got it noted on Riu somewhere) i ended up throwing in the towel and getting the T5s out, that's the only experience I've had with it.
Oh yeah i remember the thread now, iirc nutrient can't come out less than went in lol
