Ive been fighting an ongoing problem for the past few weeks. My plants yellow over2-3 days and lose all of thier fan leaves then it hits the sugarleaves turning them completely yellow and shriveling up and falling off. It seems to attack the entire plant all at once.
Ive asked and made a few posts and Ive gotten responses ranging from I shouldnt worry about it, Im obsessive, Im using just earth juice and molasses causing an N defficiency, Its completely natural etc. Im sorry but a plant 3 weeks into flower losing all its leaves is not natural.
But could it be its not getting the N it needs? I dont know what the hell is going on. I do everything right, I ph my water, let the soil dry out, keep the temps down. What the fuck is going on? I dont understand how people can grow fields of this shit and all I seem to grow are sick plants.

I would try backing off from EVERYTHING for a little while. It's the plants that I intend to kill by neglect that fucking come back stronger than ever. Damn them!

Anyway, if you're doing a whole bunch of things at once it makes it far more difficult to single out the cause(s) of the problem. Yellowing is a nitrogen issue, but it could also be an excess of nitrogen, for instance.

yeah sounds like lock out to me

maybe its a slight excess of everything at this stage have you flushed it out to see if that releases the nutes

Well I flushed them the other day and the runoff of some of the plants were as high as eight while some of themthe run off was at the proper PH. So I kind of ruled out nutrient lock out. I agree that they could be N defficient but I dont see how it could be. I feed them a heaping tablespoon of molasses and my 0-3-1 bloom with 0-0-10 meta-k. Plants dont use that much nitrogen while in bloom so if it were an N def. it would have to be pretty significant to make a plant go from green to completely yellow within 2-3 days. I think I'llgo on a mission to see what the roots of these sick plants look like. Im using EJ grow on my mothers and clones nd theyre all beautiful and healthy. Thiers lots of people that do what Im doing and have spectacular results. It frustrating to have 4 shitty harvests in a row.

prep your water ? bubble it in open container to remove chlorine ?
"brew" your feed mix for at least 24 hours ? are you using EJ grow, bloom & Cat ?
Any flowering additives ?
Soil ? possibly "root bound" ?
Seeds or clones ?

i just finished my first batch ever. i used Ej 3-part(grow,bloom,& catalyst) with Foxfarm open sesame,beastiebloomz,&cha-ching flowering additives at recomended doses, starting a little light on my mix and working my way to full strength. Came out great. i did use clear-X 2 weeks into flowering to help with a light flush. Found good recipes for EJ at 3lbs.com . http://the3lbs.com/2007/08/19/earth-...ng-philosophy/ . i shop at Northern Roots in Redding, where do you shop ?

do you pH the water before or after adding EJ, it's very acicidic.

Ej will "self correct" using its own biologicals. i tried to ph my brewed EJ and my plants hated it. went back to "brewing' or bubbling only for 36-48 hours and they are loving it again.

I use strictly EJ or pura vida grow/bloom. My vegging plants look great. Its my flowering room that looks like shit. I still havnt been able to get a look at the roots. But its still a mystery as to why these plants are sick. And yes, I ph my water after adding the nutrient to 6.2-6.4.
And I shop at garden highway garden supply in yuba city. My friend owns it.

I'm seeing the same here.

I'm starting to realize that it's rare to have healthy looking vegetation on a fruiting plant, be it an inside weed grow or a September tomato . . . it's nature, I guess.
Just like most everyone though, I want my deep green leaves deep green, even if they don't wanna be green!
That's the magic of this herb . . . you can kick the sh*t outta it and still you're gonna get some bud.
