What is causing this?

[Greenpassion]

I have a number of pure power plants and veg. 6 actually. There in 5 gallon cloth pots planted in promix BX. I've been feeding them the Botanicare line of nutrients. They get the Pro grow, Cal Mag, silica, and liquid Karma. One of the six has these yellowing leaves all through the lower Center in the bottom of the plant. The rest of the plant looks very healthy and perky and green. But the yellowness is growing rapidly. The other five get the exact same nutrients and treatment that this one gets. What could this be and how do I fix it? I've gone through the tutorials and I've looked at the plant problem section a number of times. I know this isn't bugs it's some sort of deficiency. Do I need to flush this plant? I don't know what to do here.

I use the same line of nutrients with great results too, I would think you have a hungrier pheno, if the rest of the plants are doin fine I wouldn’t change anything. It’s not like you having a severe deficiency, most likely that plant is using the lower leaves that don’t get much light.

9fingerleafs, I really love this line of nutrients. The Botanicare. My Autos are in kind soil and plain water and doing well although they are all very small because they were late. And these photos in the Botanicare nutrients have just exploded with healthy new growth. I also got a fogger for each room with six fog heads in each bin. Everything is on a humidistat and thermostats. So my environment is perfectly and steadily controlled. My humidity ranges from 48 percent to 55% in the veg room, and in the 12 12 room my humidity is 48%, whereas before both rooms were so dry I was having so many problems. I'm still having trouble getting my six clones to take root though. Its It's been 3 weeks now in the rapid Rooter plugs and every time I take the Dome off or turn the heat mat down they seem to wilt. I've never experienced clones taking this long before. I don't understand...

): there’s always the possibility they don’t root.

She may be having a Nitrogen deficiency. Being a mobile nutrient, the lower leaves will easily give it up (even paling of the leaves) in order to save the upper most branches. Any chance of a pic of the plant in question?

Do you happen to know your ppm on a full mix?

I had this exact same problem with one of my plants in my last crop. Like 9fingers said, it's prob just a hungrier pheno. I was too scared to feed it any more so the problem continued right until harvest for me. Pretty much every fan leaf fell off. I was freaking out. But in the end the plant still produced a hair over 15 oz so it didn't seem to affect the yeild at all. But whatever the issue is I wish you luck!

Underfeedinh is almost always better than overfeeding

So very true! Can't stress that enough lol.

Wow. Thank you all for your replies. Again I am not getting any notifications in my Yahoo email that anyone responded. So I have to go into the gwe app to find out. That said no I have no idea what my PPM is, and yes I will send a pic of the plant. It won't be today though. And I do hope that it's just a little underfed. Other than that all six of them are doing fantastic. Just waiting for my 12 12 room to empty out so I can move these girls into there.
