Potiental Problem, with Pic.

Th large bottom most leaves are starting to turn yellow and the very tips are turning almost brown, it feels dry and brittle. The upper leaves are not yellowing. My water is good less then 100ppm and pH is a little under 7. I did give it nutes 4-5 days ago at around 250ppm of nutes. In the picture it was watered the night before. Also my room temps are ideal at around 80-82.

Help me out, thanks. :blsmoke:
 
looks like a magnesium deficiency. you need to water and foliar feed with epson salts. consult the growFAQs for required/gallon amount. good luck.
 
I do have some of that actually! I can try when I go home. Should I foilar feed with lights out to prevent burning and if so how long before i put it back under light.

Anyone else have any ideas?
 
how old is that plant?are the leaves that look like that gettin much light?overwatering can make older leaves turn yellow like that and die.
 
Its almost 4 weeks old. I don't over water I let it dry a little before I water again. So you think I should just wait and see if it really is a over watering problem?
 
check this site out,,,,,marijuana-seeds.net/thanks-thankyou-htm,,,,,,look at the bottom leaves on the overwatered plant and then look at plants with mg deficiency,,,,,just look at the whole thing,,might help you figure out whats going on.....if its not overwatering it could just be there dying off natrually....or closet.cult could be right.
 
Well, it looks more like Mg deficiency because the yellowing did start at the tips and veins and on another leaf not in the pic it has experienced browning in some spots almost like the picture.

I will try out e-salts when I get home and see if that corrects.
