Yes i'm gonna start to run some plain water through those 3 that have 2.0EC runoff before giving any new feeding.
I'm only allowed to give 1.4EC max so that's a problem for sure, at this point i'm happy they're still alive tbh..[/quote]

By the end of flowering I am feed ing 5-6 times a day during lights on. Good luck brother

Wow that's a lot, i've clearly not watered them enough than if that's normal :o

Also I wouldn't follow any directions by manufacturers or hydro stores as they want to sell stuff. This site has been the biggest wealth of info and the only place I trust.

I've already learned that the hard way with store owners..
Manufacturers on the other hand are very helpfull or at least Plagron is, they helped me out find the problem i had in veg.
I was using RO water thinking that was the best, while the products were made to be used with 0.5EC tapwater

Thx for your help i now at least know where to start!

Cool i'm gonna look into that this afternoon thx.

10% -30% is all you need for runoff. You can also do no runoff but that means you have to run even lower ec.

I sometimes have some plants that have no runoff at all while getting the same amount of water as usual, doesn't happen often but still does, is that also a sign of something fishy maybe..?

I person ph my water for coco from 5.8-6.4. It also depends on which cycle they are in. For veg I stay better 5.8-6.0, early flower 5.9-6.1, mid flower 6.0-6.2, late flower 6.2-6.4. I change ph because at different ranges nutrients are absorbed differently. Also because as nutrients build up some ph lowers in you media.

This is once again golden info, noted down everything cheers

To bring down EC/PPM use half strength with something like FloraKleen, till it is correct. Buy a couple of cheap yellow and black PH meters on e-bay, and get 7 and 4 PH test solution for calibration. Those meters you have are a joke, for accuracy. I check runoff about once a week.

Throw away my bluelab pens and buy cheap ones on Ebay..? :O
I guess you were talking about those things to put in the pots..?

It's someone else that advised to get a couple of those to keep track of MOISTURE lvl, he also said that the ph meter on it is very inaccurate

I'll look into that florakleen that seems a good one to have in the house
I live in a godforsaken hellhole, there is no store here i have to order everything online, if i order something now i won't have it before monday.

I'm busy running plain water through them now @ different ph lvl's to try and get that ec down, i'll post every thing i did when i'm done

Thx for the help

Don't run clean water use a low EC feed somewhere around .8 ec

For the entire veg period i had nothing like this, it started happening after the switch to flowering nutes.
Water always went in @ 5.5ph (as recommended) and always came out between 6.0 and 6.2ph which seemed perfect to me.
Never checked the EC of the runoff before tho, didn't know that was a thing :(



Yes that happens a lot, they all get exact same amount of water, but runoffs that are supposed to be 10-30% are more around 0-20%
Is that also a sign of something maybe..?



They are not looking happy trust me, only nr3 is doing great, that plant has side colas that are bigger than the main cola of 2 other plants (2&4) just to give you an idea..

Upping the water frequency i'll do that starting tomorrow as they've already been fed today.
I'm not letting them dry out completely tho, they are 15L pots after all (3 and 3/4 Gallon)
The medium has never shrunken and pots still have some weight in them.

And for the moisture meter i didn't even know they existed so cheers
I just took a look at my store and they have this one, that's what you meant..?
17€ a piece so i prefer to be sure before ordering 4..

Not sure if I'm too late, but you can find them much cheaper than that. And like the person said don't bother with the PH ones. It's a total waste of money bc it's not useful at all. I have one like that, and I don't think it's ever worked.




"You need to be watering till run off or close to it at least twice a day"

Really?!?! I've stayed away from coco bc in general, it seems like more work, but watering several times a day? If the nutes work in a rez, I'd set up feed lines, a pump, and a timer lol. I'm tired just listening to what you have to do.

I did the 3 with clean water first to get that EC runoff lower, i'll maybe give them the light feeding you suggested later tonight.
First i'd like to understand why i'm supposed to feed them now
I poured water in, but the runoff was 1.2ec for those 3, so it's not like they don't have food, my target EC for now is between 1.2 and 1.4 so they have what they need..?
What am i missing

This is the results:

Runoffs from yesterday again to compare, these all went in @ 5.7ph
1 >> 4.9ph - 2.0ec
2 >> 5.6ph - 2.1ec
3 >> 6.0ph - 1.4ec
4 >> 6.0ph - 2.1ec

Runoffs after todays flushing with 0.5ec water
1 >> 6.4ph in, 5.6ph out - 1.2ec
2 >> 6.3ph in, 6.1ph out - 1.2ec
3 >> Just fed this one 5.9ph - 1.0ec >> Runoff >> 6.2ph - 1.3ec
4 >> 5.8ph in, 6.5ph out - 1.2ec

Based on the numbers i got from HQfarms i'm now in mid flower so 6.0 - 6.2ph would be best, if i did understand well they now all have acces to those numbers

They only have that one where i usually buy my stuff, i'll have a look further for the moisture only ones thx

15 ltr pots with coco is overkill for your size plants and tent.
You can grow one plant in this size pots and she will fill tent completely.
Im almoust sure run off numbers isn't part of the problems but will be interesting to see

I had 7 to start with
It's my very first grow so i chose more plants in case one dies or something so i'm not left with nothing.
The 3 others one died and 2 are outside.
Next time i'll defenetely get smaller pots.
