Hi All,

I need help ID'ing some nute issues on my Tangerine Dream & Gorilla Breath. Please see below:

[/TABLE]

First plant: Tangerine Dream (photos 1-2)
New growth has interveinal yellowing and leaf tips that are pale and sometimes curled. Leaves darken as they age but retain some of their interveinal yellowing.

Second plant: Gorilla Breath (photos 3-5)
New growth has interveinal yellowing and leaf tips that are pale and sometimes curled. Leaves darken as they age but retain some of their interveinal yellowing. I’m also seeing red stems.

Any thoughts? Thanks! :smile:

Howdy sweeper91, What gbauto said, what are You feeding the plants and under what conditions? Over all, by the photos posted, the plants do not look too bad to me.
 
Hi All, I'm using Jack's 3-2-1 formula. RH 45-55% and temps 65-75 F
It does look like a slight iron issue to my eye...
 
The ec you're running is a bit higher than what I normally see using 3-2-1.
What is the ec of your water?
Also, are you using HID or led lighting?
It makes a difference in optimum room temps.
Overall, I'm not seeing much to be worried about.
If the Fe shows up as deficient, I'd look at a Mulder chart for possible nute lock-out because of an excess of other nutes.

Recommended EC is 2.4 that's based on a test of my water I ran through Jack's. I tried that EC but kept dropping fast so I upped it to 2.5-2.6. Those figures include my tap EC which is .3
i'm using qb's. fighting cold temps, but i'm not gonna run a heater bc that's too much electricity
not quite sure what to do. common solution is to get ph in range but I've done that and don't notice a recovery in the plants
 
yeah, looks like iron to me too but pH is in range and nute regimen should be good. maybe cold, dry weather is causing it?
 
Jack's 3-2-1, humidity sometimes drops down to high 30s, low 40s but is in range for most part. weather has been pretty cold but i don't think temp is an issue either.
