Can't figure out what's causing this!

Okay here is what's wrong with my babies. Please let me know what you think. The yellowing starts at the base and works its way out. Then the leaves get really pale. Thanks for the info rui.

Your purple stems will lead the way to identifying your problem.......

I'm thinking its alot. Looks like iron, zinc, sulfur, who knows I'm gonna try and see what happens.

A lil info on grow would be helpful. What nutes and how much, ph, temps, soil. There's something that caused the problem, so info on this stuff helps to eliminate some of the possibilities, As you can see by the chart posted above. What your problem is now, may not have been the original condition that led to it.

Looks like cal/mag because the Ph is out. Dont bother adding new fertilizers until the ph is 6.5.

Okay I water with ff nutes. The water is phd to 6.7 before I water. The temps are around low 70s they are is 3 gallon felt pots and planted in pro mix. I might try and flush to tonight with water phd to 6.0 and then ph the runoff and see what I get.
