I can't say the parameters would have played such a huge role here, especially if you're running CO2 (which I'm not very familiar with). But it seems you kinda know the answer here, especially if this *isn't* a problem you've been watching develop over time and can repeat by using that product. I'm going to assume you're staying super on top of monitoring pH in and out here, too, but if not then Coir makes a good point.Temp - 79-81 with Co2 1200 45-65% rh
This always seems to happen when i try using moab. I am not hitting them hard by any means. I can slam them with Overdrive and never have problems; in fact great results. But wanted to figure out Moab and i guess i just cant win. Third try and i am going to have to tap out on this. I flush with OgBiowar anytime i make a major change in additives. I.e. amino aid to big bud to moab.
I have two that i am using Moab on and two that i am using overdrive and the OD is right in range.
If you have enough plants stop guessing and take a water and leaf sample to a lab.
So as Joe said, the pH being low on the run off is a sign of salt build up. Ok, so what if ur pH is coming out the same as going in but the ppm is not?? The last few feedings I have checked the run off, going into the plant the numbers were 780 ppm and 6.2 pH. When checking the runoff the pH was at 6.2 but the ppm was only reading ---. Is this a sign of salt (or any other kind of) build up?? And if so what would be good ways to remedy the situation?? I keep reading that flushing coco with h2o is not a good idea. I am using the Botanicare ready grow moisture formula, it is an amended coco pearlite mix. I'm still in veg and would like to get things situated before I go into bloom.ph at 5.1 means your on the verge of a lock out..below 5 is for sure lockout...
i would flush...but i read on canna's site about coco to never water is less than 0.6 EC...so when flushing i would maybe give 100ppm cal/mag, and 200 ppm base nutes...
i have not used coco yet..but sounds to me like this is the route to go...i would get EC to 1.5-2.0 in the runoff...but thats just me, others mught suggest you flush till runoff is less than 500 ppm or 1.0EC..i have not used coco so listen to those who have
to answer "what have you done"...simple...you over fed, not nute burn, but rather by consistently feeding by say 100ppm too much, it wont hurt the plant, but it will build up in the medium..causing salt buildup...salt build up lowers the ph of the growing medium leading to lockout...fist nutes to get locked out will be calcium and potassium....and sometimes when your right on the verge of lockout like you are, plants look healthy because they have been able to still take in some nutes, but not all...but by time you see there is a problem, and decide to flush even though plants are still looking healthy but you know something is up...you will see plants yellow a bit following the flush, next watering or even that same day with after the last flush, its best to recharge the medium with a 3/4 feeding, this will make sure the PH stays and does not fluctuate after a large flush...
but my experience is with soil and peat, not coco....next run i plan to try coco
What kind of meter are you using? If "---" is from the level being too high for the meter you definitely have a problem unless the meter is faulty or can only read very low PPM's.So as Joe said, the pH being low on the run off is a sign of salt build up.

Thanks for the future info :D
I want to say that it is a blue hanna ppm reader. Ill check it in things I have already have checked just to make sure it is still working, which makes me think that it is coming out to high. However my plant is looking green happy and thriving,(pic below).What kind of meter are you using?

I'm getting about a pint of run off. I haven't thought of all the nutes being used. My ppm meter reads down to 12 ppm I have seen,but thought there would be a little trace nutes in run off. I usually feed close to 800ppm and 6.2-6.3 pH. I did notice a little puckering on the leaves but have just recently started watering her every day. This being my first coco she likes the moister medium compared to dryer... over thinking things, it's too late:confused:Or the meter might being reading zero.
If it is then it means not feeding enough or all is well and being fed more might be ok. Ie. Nutes used up but water remaining is depleted of nutes and diluting the run off.
How much run off are you testing?
Plant in pic looks great. Dont panic!!! :)
Well she looks pretty fucking good, so I say DON'T go chasing numbers, just log your observations for now, and frankly, I wouldn't change a thing you're doing with her.I want to say that it is a blue hanna ppm reader.

I have an active air 2way meter by hydro farm to check the moisture level and to give a 2nd reading of pH. Ill try a slurry test too. I need to trans her in the next day or so, so I will probably flush her before I do, still not sure if a strait flush or a low ppm flush would be better :shifty:View attachment 382793
