So here's my issue. I think this is Rust Fungus. I've been going through the process of elimination for almost a month now, and this shit just keeps getting worse. I'll take any advice right about now. I've never had an issue until we moved into our new spot. Since we've been here, nothing but issues. Then when we bring good healthy plant into this place, and feed them the same exact thing there getting feed in the healthy place they were in, the new plants start to go downhill, just like all of the other. The only difference is that its colder now. And its not wet, just cold. The RH is actually around 20-25%. So its low, but it can drop below 60 in there at times. I think that whatever this is, its airborne. Could be wrong there too though. Here's some pics. Its starts off looking like this in healthy plants.... Then they end up looking like this, with there growth stunned. Anyone got any suggestions??
I forgot to add this info... What type of medium; soil or hydro? Hydro What brand and type of soil? Hydrotron Indoors or outdoors? Indoors What strain? All of em. How old are the plants? Some 3 months, some a few weeks What type of lights and how many watts? 1,000 watt, MH, enclosed, vented hoods. 3,000 watts total How far from the lights? 2 feet + What is your watering frequency and source of water? RO water. Coming out at 2 PPM, with a splash of tap water. What, how much and when was it fed? NPK? Feed every few hours. GH 3 Part Nutes, with Floraliscious+, CalMag, FloraBlend, Dutch Masters Zone What is the medium/runoff pH and PPM if in hydro? Between 700-1200 PPM, PH always between 5.5 - 6.1 What are the temps and humidity in the room? RH 20-40%, Temps 60-80 Degrees. What size pots? 3.5 Gallon Any bugs? Look real close. Havent seen any Any other pertinent info? Not anything that I havent already posted.
Your right... it does look like that, but we have 3 different PH meters that are calibrated every week, sometimes twice per week. One meter is only a week old and they all give the same reading. Its not a PH issue. Any other ideas?? And thanks for the help by the way.
im going to go with over fertilization or a root issue. is your ph droping daily. are your ppms rising daily? what would your daily change in ph be? whats your daily change in ppms? if your ph is droping and your ppms are raising you are overfed. if your ppms are staying the same. and ph is droping you have a root problem. it would be hard to belive you have a root issue with zone but you could have dead stuff in the medium which is breaking down. im guessing it is over ferted.
The PH and PPM are pretty consistant. Neither one of them ever spike. They slowly drift up and down. I usually only have to make small adjustments every 3 days, if that. The PPM is pretty low too. 700 on one system and 1,000 on the system with bigger plants. I've pushed over 2,000 ppm's on my plants before and it didnt do anything compared to this. I'm well under anything that would cause fertilizer burn. Im boarder line starving them. Their hungry for more. I've been growing for quite a while now. Usually only new growers are the ones burning up there plants with too high of a ppm. We just made a sulfur burner and are going to burn some in there tomorrow. On top of that we got some sulfur based spray and plan to maintain the issue with that. So we'll see what happens. Fingers are crossed.
im assuming its the air in that room since you seem pretty good at growing.. (also youve only experienced these problems after the move right?) check inside your walls if you can, (bug exterminators know how to), vents, etc. buy some hepa filters with that uv light inside it so it kills a lot of the airborne crap inside the room.
What is your reservoir temp? Have a flip through this and see if anything matches up. Marijuana Plant Abuse
if it was rust fungas then you would have little rust like flakes falling off of the bottom of the infected flowers, Im not sure, though could just be a lockout / major deficiency Peace proteus
We first noticed the problem when we moved. We had to temporarily put our plants in a trailer that had very high humidity. This I believe is where to problem started. As for the new room, the outter walls are all concrete. Any little holes or cracks that we have found, we have seal with expanding foam. The inner walls are all brand new. The wood, the insulation, the drywall, and the putty and paint. Everything has fresh silicone paint on it, from the ceiling to the floor. We do have a filter on the intake ventilation, but its not a hepa. We're going to get a better filter in there probably by today. We ran the Sulfur burner in there last night and plan to do it one more time tonight. Then tomorrow, we'll be dumping out all of our reservoirs and starting with fresh batches. We'll also be entering a fresh, healthy batch of teens to this room, so we'll see if they catch whatever it is thats going around in here.
One system is using old 3/4 inch tubing that we cleaned out the best we could and one of our other systems is running all new 3/4 inch tubing. Other then the tubing, nothing else is new, equipment wise.
I've never heard of rust flakes falling off of plants. If you have a link to something that i could read, that would be great. But Rust Fungus isnt the same kind of rust that you will find on metal. Rust on metal flakes off. Plants... its doesnt do that. Also Rust fungus usually only effect that tops of the leaves, never really the bottom unless it gets really bad. As for lock out. Im running 4 different systems. 3 Ebb&Flow bucket systems and one Drip/Deep Water Culture system. In every system, Im running the same exact nute mix. I scrub each system down between every plant cycle, and clean every inch of every surface. I run speacial hydro cleaners for my hydrotron rocks to prevent salt build up and bacteria from forming. I dont go crazy with my PPM strength like I see some people doing. I keep them at good levels. My smallest plants get about 500ppm, bigger plants get about 700-800ppm, fully mature veg plants get about 1100-1200ppm and the highest I get in flowering is no higher then 1,700ppm. I also run Dutch Masters Zone to keep my root zones clean and healthy. So if this is lockout... then I really dont know how it could be, or how to fix it, because I've been doing the same thing for years now.
I am almost 100% positive that this is Rust Fungus. If its not Rust Fungus, then its some other kind of airborne fungus, mold or bacteria. Whatever it is though... its airborne. I've checked every possible issue. So last night we threw in a sulfur burner and set the ventilation and fans to turn off while the sulfur burned for 4 hours during the night cycle. We're going to repeat this step one more time tonight, just to make sure that we covered every centimeter of our room. Then tomorrow we're going to flush all of our reservoirs and start with fresh nutes. Once we get everything flushed, we'll be adding a batch of 10 healthy teens into our third system. We bought Safer Brand 3-in-1 spray, that has sulfur inside of it, to keep the PH of the leaves at unlivable levels for fungus. We'll be maintain things with that spray. We'll also be installing a new filter on our intake, one that will better filter out fungi and other bacteria. After that... all we can really do is sit with our fingers crossed.
you need to remove the infected plants from the non-infected. Then destroy the infected ones cause there not going to produce much with the state its in, cause it probably stunted them. You would have to grow a few extra months before they start to look decent. It would be better to start over with some of the worse looking ones. Cause theres more chance that later on your going to have more problems with them.
are you using full strenth nutes? and is your ambient air exchange up to par? if you dont correct the flow of things then the sulfer is futile. air flow is the frontline defence against all this Fungal stuff, next is Alcohol (not bleach) spray every thing even running fans with it (not plants though) when it dries do it again. every three days spray the room again, with the plants removed of coarse. after the sulfer thing spray the plant with a Pro-tect and neem mix (dyna-gro) and really soak the hell out of em' then soakem with water after a couple hours and again just soak the heck out of em. they should bounce back real soon. use those nute you got at 1/4 - 1/3 strenth, they are all way to hot at sugested levels.
