coco run off PH high - Growing in Coco Coir - International Cannagraphic Magazine Forums

Chrono2 · 03-12-2018, 02:52 AM

so my runoff in my coco perlite mix is always much higher than what i put in (i put in 5.4 and it comes out like 6.5)
should i be concerned with this?
i just tried flushing a pot full of my coco perlite mix with no plant or anything in it and no matter how much water i put through it the ph doesnt drop, and that doesnt seem right to me.

using canna coco

Canna coco is washed and buffered. I give it a rinse of ph water at 5.8 before use and then off I go. I think it’s normal what’s happening there. The root zone ph is balanced by the nitrate/ammonium ratio. Get em in and start feeding them mate. Ph 5.8 for coco.

ok thanks for the reply and ya im gonna start using 5.8 from now on, someone else on the forusm said i should be using 5.2-5.8 but everywhere else ive seen says 5.8-6.0

Yeah mate. Ph 5.5 to 6 with 5.8 being ideal. Allows for optimal uptake of Phosphorous

Hydroponic Range

to get a correct reading on the runoff , you have to let the pot drain into a clean unused drip pan or something . if you try to read the runoff in a drip tray thats been collecting runoff for awhile , you'll get a much higher reading . just sayin ......

What is tap PH? What EC is the run off? Etc etc.

Run off is inaccurate and too variable. How do the plants look?
