It's Happening Again!

Bullshit.
Overdose= Dark green, lush, soft new growth, sometimes with a droopy look.
Underdose= Older growth starts to yellow, starting between the veins (chlorosis).

wow. i felt that smack all the way over here:jawdropper:

Rock.Steady Reviewed by Rock.Steady on 12-30-2007. It's Happening Again! So I'm in my second grow now and my plants are two weeks into flowering as of today. I've been feeding 1/2 grow and 1/2 flower nutes for the first two weeks and my big fan leaves on the bottom are starting to turn yellow again and shrivel up, same as last time! :mad: I thought it only did that last time because I fed 100% bloom nutes right when I switched to flower, so I am clueless as to what could be causing it this time around. I just switched to 3/4 bloom and 1/4 grow nutes last night. Rating: 5

DJ - As plants grow bigger and light to the lower fan leaves is obstructed by the new upper growth, it's natural for some of the lower fan leaves to die-off. Are you sure this is not what you are seeing?

What kind (brand) of pH meter are you using? Do you calibrate it? (Probably a silly question to ask you, but it never hurts to check.) Have you ever checked your meter readings against a liquid pH test kit?

How much CalMag+ are you using? Are you up to full recommended dosage? CM+ is 2-0-0, so it can be an important source of N.

I have to completely agree with Stinky. Frankly, I'd be ashamed of myself for wandering around saying things that are so off the mark for my OWN self respect and that's completely putting aside telling someone to do such a thing without caring anything about their grow.

A troll is a troll is a troll - they feel no shame or pity. Their only pleasure is from the negative reactions they cause and the peripheral damage they may do if someone is foolish enough to believe them.

He will never be allowed to post here again under that or any other name.

Anyway, all that aside, can you get a clear pic of the problem, including the entire plant and its pot?

Well, it must have been a pH problem. All the fan leaves that were yellow turned back except a couple really low ones that aren't getting much light. I raised my PPM to 1100 and the plants seem to love it. They are looking nice and green and are starting to frost already. Thanks for all the help!
