How to Adust PH in CoCo?
I've been trying to adjust the ph of my 3gal bucket filled in coco thats currently at 7.5...way to high. So i flushed it with RO ph'd at 3.7/3.8 but for some reason the ph of the container plant will not go down. So far i've already poured 10 gallons over it but it's sticking to 7.5.
I just replaced/calibrated my ph pen so that cant be the problem. Its other solution phs correctly...i checked it agains a buffer solution.
how do i bring down the ph?

Thats because you cannot alter a mediums pH by pouring pHed water through it. And if you are reading runoff to get your pH, well that dosent work either. But if you really think you need to lower your mediums pH then add some sulphur to lower. Or just be sure to add dolomite lime and some ewc to the mix before you start growing and problem solved before it even arises.

hmmmm...so measuring the runoff is a waste of time? I just need to make sure my watering/feeding is ph'd? i'm using heavy 16 and their instructions are to measure the runoff and correct if needed...not sure what to do hereOriginally Posted by Alexander Supertramp

Growing in coco I would just be sure to pH to 6.5 and grow. Read your plants, not the runoff.....how do your plants look?

they look great...i just thought that the runoff's ph mirrored what the actual ph is so i'm thinking its too high even though i'm ph'ing everything correctly.

Is 5.5-6.0 not optimal for Coco?
Runoff pH will lie too you every time. Your plants will never lie too you......

6.5 seems to be the norm for coco....5.5-6.0 is full on hydro.

Coco should be treated like hydro. PH should be 5.5 - 6.0 and feed every watering with a plain water flush every two weeks. Some flush a bit more often. Do not treat coco as soil. You will get fucked.
No it shouldnt. Neither should peat based mixes........I do agree coco needs a little rinse every few weeks. Potassium build up can be an issue when growing in coco.
