Does anybody in coco feed low ppm?

I see people talking about running 2.0 ec, the coco for cannabis GH chart tops out at like 800ppm, but I’m maxing out at 300-400ppm.

I’m using coir/perlite in 3 gallon cloth under 340w led with the GH trio and feeding once day usually. Now that said, my humidity is way too low but even still it seems weird the plants would want so little food. Lately it’s been around 80f and 40-50% humidity but sometimes rh drops as low as 30%



right now I’m running this plant that should be right around 4oz and worked up to 450ppm and had to back it off again when I started getting burn.




has anybody else been through this? It makes me feel kinda crazy or like I’m missing something.

i just finished a grow feeding 5x a day at 0.8

Jacks 321 in coco currently @ 1.0EC.

I feel you. My 3 autos are barely getting 1.0 and a quarter of that is my tap.

I stick with .8 to 1.2 (twice per day) depending on strain.

The lowest EC I've to finish a plant was 1.2 EC and that was a single daily feed in 1 gallon pots. They could have been run lower EC or fed more often. Feeding is a juggling act of multiple variables.

Keep listening to your plants, they're all different. Lookin good!
