DWC Help

[PoopyTeaBags]

OK guys this is whats going on... I got a 12 bucket dwc going we are about 35 days in flower.

Everything was good we were bumping the ppm's up 100 a week.. We got to 900ppm it was fine....went to 1000-1050 and we started to get burns and bottom leafes started to die... so we backed off the solution to 800.... Now the plants have not ate any nutes for a week... They have been drinking a shit ton of water and and it messes with the ph alittle but will not take up any nutes...

We changed the water out back to 800ppm about 5 days ago still has not moved the ppm just he ph and drink water like mad...

Am i locked out? Should i flush with plain water for a day? is it normal...

Also im told that a pistil here and there are going brown... Im going over there tomorrow morning to look at everything... Any help would be appreciated.

Am i locked out?

Could be, what's your ph and which way is is drifting.

 

[PoopyTeaBags]

ph used to sit at 5.8... I cant remeber which way its drifting but we usually have it at 5.8

what does it mean when it drifts up and/or down?
root rot?

I have a chiller water temps sit at 68 degrees but when we changed water last time we left it off for half a day got up to 74 degrees but it was only half a day and problem began before we changed the water...

Root root could explain a precipitous drop in pH, this doesn't sound like root rot.

If it's drinking solution and your TDS remains the same, it doesn't mean it's not eating nutrients, it means you have found the correct nutrient concentration for your strain, that your plant is taking up water and nutrients at the same ratio you are supplying it.

Sounds like your doing well!

 

[Haps]

Drifting up will do no harm, and can even help late in bloom, as long as it does not go to 7 or above. Nothing you have told us explains or exhibits a problem really. You make changes, entities take time to adjust and regain momentum I reckon. Toss the PPM pen, a good nute strategy is better, ain't used one in years.

Is my advise better when I ain't on my high horse poopy? Or is this horse still too high?

what would the pistols turning brown mean? just one hear and there...

also you say its drinking at the same im supplying it but i got plain water on auto top off so if its drinking solution and water wouldnt the solution concentration go down as it adds plain water back?
cause if it drinks 50ppm with a gallon of water and it adds back a gallon of water wouldnt it be 750 ppm? its been sitting at 800 ppm for over a week.

hehe i appreciate the advise even when i cant hear ya from your horse being so tall... -=P always appreciated haps no matter what i say lol

Correct, if it is drinking and ppms go up, then it is not eating nutrients. There should also be a corresponding slight ph drift up. This kind of drift is fine.

 

[guest456mpy]

Don't sweat the occasional pistol darkening, it just happens.

 

[PoopyTeaBags]

well you guys are making me feel alot better i was expecting to go over there and flush the whole system for a day or two and then get back on schedule.

 

[bendoslendo]

Yeah that a bit more concerning if your auto-topping with plain water. Are you sure they are drinking?

Most important question, are the plants growing?

 

[PoopyTeaBags]

The plants are done stretching so i cannot tell you if they are growing... They look normal they are just not eating.... since im auto topping off with water that means that they are not eating the food just water...


so should i be flushing tomorrow?

Correct, if it is drinking and ppms go up, then it is not eating nutrients. There should also be a corresponding slight ph drift up. This kind of drift is fine.

EC up is NOT synonymous with fasting. Plants can gorge themselves as EC climbs depending on other varibles.

EC and pH should move in opposite directions. If they're going the same way something's hinky. Nutes are acidic. Add nutes (EC up) and acidity increases (pH down). Subtract nutes (EC down) and acidity decreases (pH up)

I do EC up for 20 weeks and more. It's the key to my system. EC up does NOT mean no eating. It simply means she's drinking water faster than food. I let EC rise and pH drop for 2 weeks, at which point tap water raises the waterline, decreases EC and raises pH to original levels.

A brown hair or two simply means she's maturing.

 

[bendoslendo]

If the plants look healthy and are taking up solution I would definitely not flush tomorrow.

Even though they have stopped stretching, some swelling and additional calyx should be forming, with new pistils popping up.

 

[PoopyTeaBags]

Right so lets get a real answer on why the plants are not eating its been more then a week with auto top off water. She drinks water but has been at 800ppm for over a week while drinking water... So they have not touched nutes in over a week... should i be concerned?


sorry seemed like some say yes other no... and im just getting confused.

 

[FreezerBoy]

She drinks water but has been at 800ppm for over a week

This proves plants ARE eating. If plants were fasting, EC would climb drastically as the waterline and pH drop.

 

[FreezerBoy]

Should've said this earlier. While EC and pH remaining flat does mean the plant is eating and drinking at the same rate, it does NOT mean the plant is eating N, P and K at equal rates.

Some nutes are more available at low pH, some at high pH. Flat readings over time can lead to res imbalance. A small pH swing is better for you.

EC movement alone is neither good or bad. It is both symptom and tool. Rather than be a victim, a puppet to the symptoms, be their master. EC and pH move at your command at whatever speed and direction you desire.

This proves plants ARE eating. If plants were fasting, EC would climb drastically as the waterline and pH drop.

Even with a auto top off rez that tops off with strait water? The waterline does not drop with a auto top off rez there for the EC will not climb... it remains the same to me this would mean that they are drinking water but leaving the food ie not eating/fasting...

This is a RDWC just to inform ya its a 12 bucket set.

 

[PoopyTeaBags]

the ph is drifting down....

 

[FreezerBoy]

If EC remains flat with auto top off, that means EC is climbing but, the water brings it back.

EC up, pH down is THE classic example of overfeeding.

we did have it too hot for three days went from 900 being fine 1000 to hot was there for 4 days then brought back down to 800 where we have it and it sits....
