I Got a Problem for the Pros to Figure Out

I grow aeroponically in a two teer vertical octagon system plants are contained in 6 inch tubes.... 16 plants per tier no medium, just air, roots and nuted water.... I have 24hour a day meters reading my tds/ppm, ph and water temps.. I am 3 weeks into flower right now and running connoisseur as my base, no higher then 500ppm so far. PH is between 5.5 and 6.5 atalm ti
es with natural fluctuations and water temp is never above 75 but usually around 70... About a week ago I noticed one plant in the middle of the top teer turning very yellow and all other plants are healthy as can be, I am now noticing the yellowing in the plant next..... This is not the yellowing that happens later in flowering... This is something wrong.... I have been growing for 20+ Years and am stumped.... I'm guessing it's some kind of root disease.... But since my plants are caged in, there is no pulling them to check the roots.... Huge propps if anyone has a good thought or strong notion of problem and cure

pics pics pics.

All pictures are going to Show is a plant going yellow super fast amongst a bunch of green ones... Really shouldn't be necessary for diagnosis

just a suggestion. see how many replies you get without pics compared to those with pics. believe me, it is true, a picture is worth 1000 words.

And then you look at the pic and see my couple hundred words described exactly what I explained.... I do understand the relevance of pictures, but the right person won't need them in this case.... Appreciate you lookin out though...

Im not psychic and a pic is worth a 100 words, good luck

I'm not psychic either and don't have a clue why that had to do with anything, but thanks for chyming in on how much you like pictures

I am psychic let me try! Seance music playing in the back ground, candles lit, turban on, crystal ball all aglow ready to figure out just whats wrong with your plants. AHHHHHHHHHHHHHHH holymoly big fat conoli please tell me whats wrong with this mans plants....................... Ahhhh the crystal ball is getting brighter its getting ready to tell me...... wait wait Ah crap! Sorry man the crystal ball says he needs to see pictures too

Maybe if the solution is too weak or if the water flow is too high the water could somehow leach the plants like when flushing, and since it's happening in a progressive way and to the plants closer to the intake then it could make sense. However I just threw a stone, I'm also interested to know the real answer.

Well without pics its going to be hard to help im willing to but your going to have to meet riu halfway

I also grow aeroponically. The only thing i can think of is a root disease in the one plant (in which you will want to chop it down and take the roots out) or it's underfed, but that doesn't seem to make sense as you say the others are fine. I start my girls at around 900 ppm in the first week and pump them upto around 1200(or more if they allow). I'm not sure why you started at 500?

If there are no signs of the other plants on the same tube doing the yellowing than the best logic answer would be root rot or some sort of root disease. You have to think..that plant is taking in EXACTLY what the plants next to it are taking in. Hope that helps you

I checked my water level to see if it was pooling at all and it's not and the solution is definitely not too weak because the rest of the room has realy light signs of burn on the tips... That was a good toss though for sure....

I run at 500 because I use connoisseur, I'm in aeroponics and you run way less then normal feedings normally.... If I ran 1200 they would just catch on fire....

check the spray jets on both sides of that plant, i bet one of them is clogged.

this is strain dependent, i run mine as high as 1700-1800 in full bloom. With no signs of burning up. Just have to see what the strain you are growing will handle.

Think immobile and mobile elements friend. That will help u determine which nutes to rule out. Because certain nutes are only eaten at certain ph levels. That why when it rains in nature our ladies droop because rain is 5.8ph so it locks some nutes up whole the plants get some of the mobile elements and immobile. Think of downward causation. What does the plant do in retrospect. She metabolizes nutes turns them to carbs and sugars. So from sun to leaves to energy to growth. If it starts at the bottom u know they are immobile. If it's at the top its a mobile element. Here should be a list of which are which along with a ph table showing where certain nutes will get locked up. That should give u the resources to learn and fix ur own problem. Ok so where did the yellowing start? Top or bottom. How quickly did this occur? 1-3 days 2-4 days... Did it happen over a dark cycle? How about the color of yellow. Is it a complete yellow or is there signs of green? Is she droopy? Any rusting on the leaves? This is where pics would come in.

Once you figure If it's immobile or mobile u then can decide the best way to take action. I think u should just pull the bitch out and examine her corpse to see what the fuck she is doing. You have more plants right??? Just kill the bitch and learn from it.

U could always do a clearex flush then re nuts ur res

For the guy that says he runs up at 1700 in aero, I run 8 strains at no higher then 800 in the whole cycle and they will all still hae signs of burn.... If you want to talk o somebody that likes to hang out on here and post pics that you can talk o about aero and nite loads, go talk to Earl and see what he runs at.... As far as the guy that said pull the bitch.... Not a bad idea, I am just irritated that they all share the exact same environment and water and are all contained in the same tubes, so to not have a solution just bugs the shit out of me....

If anyone knows how to get pics on here from iPhone I will post some.... Yellowing started at bottomed and has moved rapidly up and the whole leaf yellows, like complete nitrogen lockout, it's not any mag problem and like I said they are all in the same system, so if there was a mute prob it would be everywhere, not just this one area
