Other the last couple of days the leaves of some of my plants have begun to turn up along to edges, as the photos show. Anyone seen this know what it is? I've looked on overgrow's grow faq for sick plants etc and can't find anything.. Info of grow: Hydroponics, pH is around 5, air is ok, nutes might be a prob though, should I flush the systen and start with fresh water/nutes? Help?
It looks like your plant is upside down..you might wanna fix that In other words, im not too sure. You might wanna raise your pH alittle if you could. I wouldn't flush right away they still look healthy.
So you think that I should try to cool it down, which means wait, I've already got/had a fan circulating the air, it's in a closet so it is sorta confined, with 4 42w CFLS. They aren't turned brown yet so i'm confused
I actually was concerned with the pH, I took it this morning and it was around 6.7, so I fixed it down to about 5, which it was at when I started. Maybe the plants are running out of nutes since it's been about a week? That might explain the rise in pH since the salts might be raising the pH
Atokeaday is right. That curling up of the leaves is from heat stress. Also get your ph back down into the 5's; that is critical.
Awesome max, could you or someone write out the abbreviations that are displayed at the top of the chart? Might be hard to search for concidering the facts.
It's not in the same order as the chart. Nitrogen (N) Phosphorous (P) Potassium (K) Calcium (Ca) Sulfur (S) Magnesium (Mg) Iron (Fe) Manganese (Mn) Zinc (Zn) Boron (B) Molybdenum (Mo) Copper (Cu) Max.
Also, someone posted this pic to GC and shows that if the PH goes high or low some nutes are unavailable and the plant will show a deficiency. So that does not mean that the element is not present and in the correct amount.
Ok so I'll change the water and nutes and reset the pH down to about 5-5.5 and put 2 teasp. of nutes in instead of 1 per gal.
So the curling is continuing, yesterday I set the pH down lower so I guess i'm just going to try a full water/srub/new nutes change
sorry, can't help you but; what are you growing in? i've seen it around before but can't remember the name Does it require as big of a pot as a soil grow?
In hydro if ur PH was 6.7 and rising then the elements FE B P become unavailable, MG harder to absorb by the root system. I suspect that it's the result of that so just get the feeding sorted and hope they recover.
I posted the same question late last week and no one answered ... Mine are doing the same thing, they are getting better now... I changed the water went back to 50/50 and lowered temps to 70-80. I only have about 7-10 turnrd leaves now.. they were all that way. My PPm had raised to 787 and Ph went up just like yours. heat stress seems to be the answer good luck
Hopefully that's answer is just heat, or the nutes. The heat i'm trying to deal with, I have a fan on them at all times, but not pointed at them all the time. Also I put the pH back down, but tonight I'm going to change the water completely and add new nutes. BUDSLiNGER-It was the outside temps right? Not the res temps.... Will the leaves ever uncurl? Ladybugs help with aphids/fruitflies right?
Hydroton Clay Pebbles No, the netpots that I have them in are only 5in wide, since the roots rest in water they don't need a big container for the roots, ie they never get root bound.
This only happened to mine after temps reached 83 and above. In the grow area,Im still fighting the temps to keep them down but the cooler air helps allot. Im trying to get 75 as the running temp, Ive read 70 is to cold. I also have very good air flow but when its that hot it just blows heat around...At night when the light is out they get to about 67. Ill keep you updated.. There are pics I posted called 3 week b day.. you can check them out posted here in indoor grow..
