They are super blurry. But you can kinda make out that they leaves shrivled up and jsut died off no signs of anything.
I got a no pest strip hanging so i dont think its bugs.
The PH just keeps dropping. I get it back up to 6 and then it just falls down way past 4. I gotta add another 1/2oz of PH up every 6 to 12 hours.
I use dyanagro grow. Calmag, it happened before, so I added some protek and it dint change a thing.
Wondering is this strain is some how wanting more water? But with the PH changing so much im sure thats killing the plants. But WHY does it keep going down?

root rot will lower your ph i learned this while reveging in dwc

Those plants look freaking dead. Now root rot does lower ph pretty quick so check it out now. and they look like they are THIRSTY and look like you need stop adding more nutes at this point.
root rot? I dont see any roots other then a view visable when i pull the buckets up.
I did notice some of the rockwhol cubes had a green fungis growing on them when i moved one of them over. also ones got some blackish white stuff on the rockwhol cube from where it wasnt covered.
I dunno if that would cause the PH balanced problem but eh. i was comtimplating speeding up their feeding. at the momment they get watered 3 times a day 2 minutes a cycle. the plants were doing fine with this until about a week ago and one died the other looked fine and then over night it jsut died off.
I need some help =\

How about the FULL details of your setup, environment, nutes and H2O source/ppms/PH?
The more info you give, the more likely the answers will be accurate :wink:

Did you read my last post at all?
ph should be at 6, i cant see how my ppms and my water source is gonna tell you why my PH is dropping.
Its a DWC bucket system. Water is in a 5 gallon to 2.5 gallon to 7 pots.
AGAIN i dont know wtf this would have to do with anything of my PH issuing considering that i ADD ph up to the MAIN circulation bucket. This is common for this kind of setup...is it not?
The PH unbalances every time i water. This is what leads me to believe that there is an issue with somthing on one of the plants but how am i going to isolate it? Just wait until its dead?
Again this environment means jack to this situation as well. As I have been running plants in this room for almost a year with NO problems.
The room is 3x15 halved. One side flowering the other side veg. the only problems are happening in veg. The plants were FINE until about a week ago when I discouvered the PH has dropped in the toilet. At that time one plant died. NOW i notice two more are dying. One is actually dead the other i see some green growth on. but the rest of its leaves are shrivled.
I already SUPPLIED nute info. BUT LETS break it down alittle furture.
My Mix:
4 Gallons Water
4Tsp DynaGro Grow
2Tsp Calmag
2Tsp Protek
1tsp PH Up
Brings me up to around 450PPM and a PH of 6.
After one water cycle im back down to a PH of 4.
WTF?
PS i hate repeating my self, notice?
Hey dogmeat it doesnt look good at the moment and quick action is needed. if it was me i wud empty all pot and circulation containers, ph balance some water and sit with it while it constantly circulates thro, check out coming ph regular, as soon as it starts to drop, empty the sump bucket and fill it again with ph balanced water. keep doing that and c if it stablises.
did u soak and ph balance yr rockwool and clay pebles first?
the ph going up and down will only make them worse, so if u've got the time sit with them and keep putting in balanced water, try to get a constant.
i'm not sure if the other guys wud agree buy imo yr plants wont b interested in nutes at the moment, til they start taking in som water and not acid.
Good luck man. i'll lite a candle and do a rain dance, it mite not help but it'll b fun!

Yes...you still left ALOT of stuff out that could be causing your problems tho.

If you're feeding em too much it'll often make the PH drop. Likewise the water source/ppm/ph will tell you what's in the water that might be buffering the PH...possibly leading to lockouts from calcium, sodium or chlorine in the water - not to mention lower temps making the water capable of holding more acidic gasses and warmer room temps forcing the plant to transpire more moisture.
It is normal to have to add PH up occasionally...but if you're having to add that much that often, it's a sign that something isn't right with your setup/plants.
In one of the pics, there appears to be some very OD'd plants...and they're the larger plants. I can only imagine that the nute levels are slamming those little clones. Yes I know 450ppm isn't that much, but it's often the stuff that doesn't register on a TDS pen that can cause alot of the problems. Were those plants getting a different feeding that damaged them or did the damage coincide with the small plants starting to die?
The feeding on those plants started a while ago. I run a cycle, every 3 weeks new plants get put in and old plants get moved out. Right now with sick plants my cycle is broken. No more solid crops for me 
Those plants have been damaged for a while but seem to keep being damaged by the change in PH. Im sure they get watered once, then thje PH goes askew and then they get watered again and it just hams them out.
The reason those plants looked burned is because i went in there one day and the PPMs were around 900, which ive seen kill my plants w/ this TDS meter.
What im gonna do is measure the run off of every plant this after noon.
IE, move all pots but one out. Water it, test the water if it stays the same then good, take it out put another one in and check it that way. atleast then i know which plant is the offender. The res i believe is almost 100% empty.
The room temp is usualy about 85dgree's all times. The Realative humidity on the other hand is always about 30% most of the time aorund 40-50% which is bad. Cant run a dehumidifier in there until i get better wiring.

So you've been running a cycle for awhile and things are fine.
All of the sudden after the addition of only a few plants, you're having pH issues.
What else did you add to your setup besides the plants?
I'd like to say since this combination of nutrients is obviously not working, why not try something else. Plain water for a few days.. raise the light... Or maybe just 1/2 strength grow for a couple of days.
But it has worked for you all along, until you added a few plants?
I searched for DynaGro and Protek on my hydro site and found no results.
What are you using to test Ph? Just curious.

For PH I use general hydrponics. Dyna-Gro is actually a pretty popular fert. Even tho i plan on moving away from it when the bottle is gone.

Nothing else has been added or changed. After the first plant died off, I flushed the system and added some protek still no change.
I did notice on the other hand the one that really really went shirivled up and died off, its got some new leaves comming back to it. Maybe it will come back around.
Ill keep you up to speed on this. If anyone has any idea why the PH would keep going down please post.

I noticed the Protek has Silicon in it. When I use Silica Blast on occasion it causes major Ph swings. Unfamiliar with your main nutrients, I would back of the PPM and Protek and see if they recover. Treat them to some spring water if you wuv them.
Do you even need Cal-Mag? Have your plants shown you so previously?
Do you even need Cal-Mag? Have your plants shown you so previously?
The plants were having a deff in both veg and flowering. So i added calmag just to see. Asking the local hydro guy, he said the first deff you see using dyagro is a cal/mag deff. So i started adding that.
Now check this out. I just went and took one of the dead dead plants out of the equasion.
I took 3 gallons of water. Added NO NUTES. Ph'd to about 6.2ish and then dumped 4 cupfulls (a dennys metal shake cup) worth of water onto each plant. Then measured the run off for PH. everything looks fine?i guess the enxt step is to see if there is any water hanging on the bottem of any buckets?
They feed in a few hours, ill re check it before i go to work. For now Ill take a nap.
PS one plant atm is showing signs of under watering. Which is odd....can a PH lock stop them from getting water?

Here is what your feeding your plants with the dyna grow and cal mag plus:dogmeat said:
n 106
p 52
k 55
ca 48
mg 15
K is too low. It should be closer to 100 or more. K and Ca are almost equal. This is not desirable. Quick fix would be to stop the cal mag plus and add only epsom salts. Magnesium being low is the problem with the dyna grow grow. (calcium and mag are low in the bloom)
In 4 gallons:
4teaspoons dynagrow grow
Add 1/4 teaspoon epsom salts to increase ppm mg by 8. (very little really)
This gives you:
92 n
52 p
55 k
26 ca
7 + 8 = 15 mg
You can see you now have a ratio of 4 parts potassium, 2 parts calcium, and 1 part magnesium. This is a good starting point.
Yeah it does (0-0-3)...as well as serving as a PH up. I stopped using PH up since I started using it a few months ago and it seems to work just as well while providing them extra heat/cold resistance.
I think you're on the right track flushing them tho...is there any way you can isolate the buckets to see if maybe a root disease has set in on one of the plants?

no....i cant seperate them out. I wish i could....
After flushing them this morning i had seen no change. Now i come in at 5pm they fed around 10am. The water is back to about 5.5
I suswpect that if i let it feed that water at 6pm that it will go all the way into the 4's.
It deffinitly would be nice to know wtf is going on.....root disease...any good way to tell this without pulling the plant out?
