Need to figure out why ppm steady pn the rise.

[Bucsfan80]

Don't know why flower has been a bitch, maybe because veg was a breeze idk but been having problems since flower started.

10 gal dwc 3 site. 2x white rhino 1 Skywalker og.​

Weekly rez changes and rinse hydroton till ppm is same as tap water (65-75 ppm)​

Calimagic, GH trio nutes and S ag. Bennies.​

Water temp between 68°-72°, temp at canopy 70°-80° (don't get that high now about 77° max since cooler weather. Rh 45%- 55%. Ph6​

After rez change ppm will rise everyday 70 to 80 points I add water to dilute but next day back up. Don't know what is causing it any advise or thoughts? Thanks!

I feed as follows calmag 25ml about 250ppm then micro 25ml, grow 25ml bloom 70ml came out to 730ppm after phing total ppm was 760 and in 4 hours was already 790ppm

here ya go...

I have went by that that and lowered EC from almost 2 down to 1.4ish just trying to figure out what to do during the week between rez changes cause I can't afford to put nites down the drain every come days was hoping someone had some advice based on experiencing the same kinda thing.

You have more roots now with not much water,3 plants in 10G of water ?Work with what you got,1-1.2ec should be fine.Just add water as they drink.Changing water out weekly is going to be the norm.

I add plain ph water daily. So go lower on the ec then?

I would lower ec until the ec stabilizes better with water level. What week of 12/12?

Like week 6½

What's the best way to lower it? I've been feeding at 50% of recommended so this time I cut calmag in half (have been using full strength) and the micro I used 25% this time
Figure nitrogen is the thing to go light on

Yes week 7-9 lower ec there drinking still just not eating as much.

10 gallons isn’t very much, I would 1:1 remove nute water and replace with plain water to reach desired ec.

I might give that a try after a few days. I just changed last night with lower than I have been concentration so ill see how they react

Sound good, the response will be a bit slower with a shorter light cycle too (in my experiences), maybe a couple days at 12/12 compared to 24 hours at 20/4.

I'm seriously thinking about throwing ec meter away. It just complicates things and if you have a decent nute line and PH regularly I think all would be fine

 

[Bucsfan80]

Ita a 10 gallon tote that always has 10 gal in it and as much root system as they have there is still plenty of room under the water line for more roots so I guess I figured it was enough but I am a noob so ill be upgrading after harvest

When you change water do you let it flush for 24 hrs drain and refill with nutes?

 

[Bucsfan80]

Elaborate a bit more please. I usually empy completely and rinse it out take a suffer pad just dont use anything but water and monthly I flush the hydroton from top till run out is same ppm as tap water

The roots need a flush every week,so we change the water out, i go higher with the water level to submerge the roots.After 8 hrs or so check with ec meter if its close to tap water there was no build up if its higher then tap say by 200 ppm ill flush again.In my rdwc system il fill drain 2-3 times in one day if i get a build up.Hope this helps .

 

[Bucsfan80]

Ok so me flushing from the top down till tap ppm is about the same but I think your way is more thorough and I will be adopting that method thank you very much. What ppm to you run during flower?

 

[Bucsfan80]

10 gallons isn’t very much, I would 1:1 remove nute water and replace with plain water to reach desired ec.

So I cut rez solution down everyday by as much water as I could add and monitored it until I hit around 750-770 ppm and I noticed they drank at least a gallon over a day time cycle and ph stayed static and ppm stayed static so only solution level was dropping so instead of topping off with just ph water I topped off with a gallon or two of nute water and that seems to be the magic ppm range (750-770) I thank you for your advice and am now having to add at least 1 if not 2 gallons a day. Bad part is I'm getting low on nutes and new won't be here till Monday or Tuesday. Think I have enough to keep topping off just cant do a full change till then. Just thought I would update with the results
