rust on my blueberry girl!oh shit!

[chongsbuddy]

I have a feminized blueberry from DP in a cup with 30% promix and 30% perlite,no other nutes,plants have been sprouted for about 2 weeks and are under a 30 watt flouro,1 inch from light.I went away for 10 days and my friend looked after my girl while i was gone.I got back and she looks fairly good except for some rust spots on the first set of true leaves.I forgot to mention that i,or sorry my friend sprayed her once a day with a light kelp spray.Thats all the info i can give,i have some pics,anyone know what it is?

nobody?

That looks odd and more like insect damage to me. Are there any bugs around?

Chongsbuddy,

you say you are in promix with no other nutes, but correct me if im wrong, but isn't promix inert? Either way, why no nutes?

Also, could be just me also, but, that looks like light burn to me a little too.

I could be way off base about all of that though.

Pro mix has a shot of nutes and plants that small shouldn't need a feeding yet.

light burn, move it away. its a flouro and all but the leaves will still dry out and burn with prolonged exposure.

 

[chongsbuddy]

thanks,i'll move it away!

It could perhaps be light burn, but if you haven't moved the lights before, how come it didn't burn the top leaves?

Since the new nodes seem to be healthy, I wouldn't worry too much about it. Blueberry is a very picky strain that can react curiously to slight abuse while other strains don't. The genetics is known for mutations and leaf deformations. I've seen twisted, scraggly looking leaves on Blueberry plants, and there was nothing wrong with them.

Common types of Blueberry deformations:



Nevertheless, if your friend has been foliar spraying every day, it could very well be some type of isolated leaf burn.

It's my best guess.
